Are Chickens Immune to Snake Venom or Does It Kill?

Have you ever wondered are chickens immune to snake venom? Apparently, this is one of those popular beliefs, like a lot of myths, amongst many old homesteaders with no real known origin. Let’s unpack this topic while we answer the question.

​Are Chickens Immune to Snake Venom?

​The short answer is no. Chickens are not immune to snake venom. 

​On the contrary, folks seem to think that chickens are immune to snake venom because they believe they’ve seen them suffer a snake bite. Then, they see no adverse reaction or complications, thereby assuming their immunity.

Truly, the chicken owner has probably seen the snake strike, but it didn’t break the skin of the chicken with its injecting fangs. Chicken feathers help protect them against an envenomation by deadly snakes.

Chickens are incredibly agile, with the ability to bob and weave and jump out of the way quickly to avoid potential harm.

Understanding Snake Venom Composition

Snake venom is a complex mixture of proteins, enzymes, peptides, and other substances that varies among different snake species. It’s primarily made up of proteins and enzymes that serve different purposes when injected into a victim:

1. Enzymes: These are special proteins that speed up chemical reactions in the body. In snake venom, enzymes known as phospholipase a break down cell membranes, causing damage to tissues and disrupting cell function.
2. Neurotoxins: These are venom components that affect the nervous system. They interfere with nerve signaling, leading to paralysis or muscle weakness by blocking the transmission of signals between nerves and muscles.
3. Hemotoxins: These toxins affect the blood and its clotting ability. They can cause hemorrhaging by either preventing blood clotting or by breaking down blood vessels, leading to internal bleeding.
4. Cytotoxins: These are toxic substances that damage cells directly. They can cause tissue damage, pain, and swelling at the site of the bite.
5. Other components: Snake venom may also contain components that affect the cardiovascular system, causing changes in blood pressure and heart rate, as well as substances that can disrupt the immune system.

Effects of Snake Venom on Chickens

Snake venom can affect chickens in a manner similar to its effect on any other snakebite victim. The impact of snake venom on a chicken can vary depending on the type of snake and the specific components within the venom.

When a snake bites a chicken and injects venom, it can cause a range of effects:

1. Local tissue damage: Venom can lead to swelling, pain, and tissue damage around the bite area. This can vary from mild irritation to severe damage depending on the venom’s potency and quantity injected.
2. Systemic effects: Depending on the composition of the venom, it may contain toxins that affect the nervous system, blood clotting, or other bodily functions. This can result in paralysis, muscle weakness, difficulty breathing, bleeding disorders, or other systemic effects.
3. Death: In severe cases, particularly if the venom is potent or if a significant amount is injected, snakebite can be fatal for chickens due to the venom’s toxic effects.

Do Chickens Have Any Resistance to Snake Venom

​No, not only aren’t they not immune to snake venom, but chickens aren’t resistant to it either. Again, they do have the ability to avoid a snake bite easier than some other animals. 

Additionally, chickens have a super fast metabolism compared to other animals, and they can often times neutralize a toxin quickly. There are published studies that show chickens’ ability to do this with some snake venoms.

Specific Treatment If Your Chicken is Snake Bitten

A venomous snake bite is very serious to a chicken, and medical attention from a licensed veterinary should be sought to help save the chicken. That said, most homesteads and small farms can’t justify a vet bill on a chicken that is worth $20. It sounds harsh, but it’s the reality of farm life.

On our farm, if I see a chicken suffer a snake attack, I would first isolate the chicken in a cage. If a chicken suddenly goes down, or become lethargic, the rest of the flock may bully it. Removing the injured bird will help keep it safe from the flock.

Next, try to get a closer look at the injection site and wash it with a saline flush followed by an antibacterial wash. Iodine or diluted chlorhexidine are great options.

Avoid cutting the injury or attempting to suck the the venom out. This doesn’t work and will most certainly put yourself in potential danger if you try to do this with your mouth.

​Last, monitor your chicken, watching for worsening in behavior, swelling, or tissue necrosis. You can push fluids with electrolytes and feed it high protein feeds such as scrambled eggs. 

Your chicken will either recuperate within a few days or symptoms will worsen. Watch for clinical signs of infection at the envenomation site as well. Remember that sometimes the most humane and ethical treatment is to euthanize the chicken.

Allergic Reactions and Possible Infection

​Even if your chicken is bitten by a nonvenomous snake, there is a possibility of allergic reaction or infection. 

Nonvenomous snake bites typically don’t inject toxic substances into the bitten area, so the reaction tends to be less severe compared to venomous snake bites.

However, even nonvenomous snake bites can cause localized trauma, tissue damage, and potential infection at the site of the bite.

Bites on sensitive areas or vital parts of a chicken’s body, like the face, might cause more harm or discomfort.

If a chicken is bitten by a nonvenomous snake, it’s important to carefully examine the wound, clean it thoroughly with antiseptic solutions (like diluted iodine or chlorhexidine), and monitor the chicken for any signs of infection or adverse reactions. 

​Do Chickens Kill Snakes?

​Maybe. 

Do they? Yes. 

Will they always? No.

Chickens may or may not kill a snake when they see it. Just like all small creatures, small snakes make an easy target for a mass of birds inside of an enclosed coop. If one wanders near your birds, they’ll probably make a meal of it. 

However, larger snakes may invite themselves in without worry of the chickens. There are countless stories on backyard chicken forums of finding a snake in the egg box with chickens.

Do Roosters React Differently to Snakes Than Hens

Roosters play an important role in the safety of your hens. They see threatening wild animals and proactively defend their ladies. They are likely to attack a smaller snake quickly. 

However, even a rooster often knows the signs of a venomous snake, and they’ll probably leave larger snakes or venomous snakes alone. Because of this, you may find the occasional rat snake in your coop helping themselves to one of their favorite food sources, eggs.

Are Chickens Afraid of Snakes?

Maybe. Chickens, like many animals, have natural instincts and responses to potential threats, including snakes. In general, chickens can exhibit fear or alarm when encountering snakes, especially if they perceive them as a danger.

They might vocalize, exhibit alert behavior, or try to stay away from the snake. Some chickens may even attempt to peck or attack the snake if they perceive it as a threat to their flock or territory.

Chickens have innate survival instincts that may prompt them to be cautious or even alarmed when they sense a potential threat, such as the presence of a snake. Individual chickens might have different reactions based on their breed or temperament.

If chickens are raised in an area with a lot of snake activity, they might be more accustomed to them and potentially less fearful.

Are Snakes Afraid of Chickens?

Chickens, especially in groups or flocks, can act as a deterrent to some snakes due to their noise, movement, and potential for pecking or attacking when they sense a threat. Some snake species might be cautious around chickens because they could be perceived as predators.

Snakes have their own set of instincts and behaviors, and while they might not necessarily experience fear as animals with higher cognitive functions do, they often try to avoid situations where they might be attacked or harmed.

In areas where snakes and chickens coexist, snakes may be deterred by the presence of chickens due to the risk of injury or harassment. However, this doesn’t mean that snakes won’t approach chicken coops or areas where chickens roam.

Factors like the type of snake, the availability of food, and the snake’s motivation to hunt or find shelter can influence their behavior.

Does Keeping Chickens Repel Snakes

​Simply having chickens doesn’t necessarily repel them, but their added activity to your homestead may help keep snakes away.

On the other hand, another kind of fowl, the guinea, does repel snakes. They are one of the best animals to protect chickens. Not only that, guineas will alarm as a group when they see a snake, and the group will attack them. Most impressively, a flock of guineas will actively seek out snakes in their territory.

Guineas aren’t immune to snake venom either, but their skin is much thicker, and their claws much sharper than that of the chicken. They have no problem tearing apart many snakes, whether they’re smaller snakes or larger snakes, whether they’re venomous or nonvenomous snakes. They work together to harass, peck, and claw at a found snake.

Will Chickens Eat Snakes?

​Yes, chickens will eat snakes, especially smaller snakes.

How to Protect Your Chicken Coop From Snakes

The best form of protection from snakes is to make sure you keep them in a reinforced coop. Using hardware cloth with smaller holes will keep even garter snakes from getting in to eat eggs or chicks.

Remember, you want to make sure they can’t get in. Chicken wire is too large of spacing in my experience to keep snakes out.

A hungry snake can often fit through small spaces, then eat some eggs or baby chicks, then they can’t get out. The last thing that you want is a snake stuck inside of your chicken enclosure.

What About Snake Repellents?

Snake repellents come in various forms, including chemical sprays, granules, electronic devices emitting vibrations, and natural remedies like sulfur, cinnamon, or essential oils. However, the effectiveness of these repellents in deterring snakes can be variable and often depends on several factors.

1. Type of Repellent: Different types of repellents work in different ways. Chemical-based repellents often rely on strong odors or tastes that snakes find unpleasant. Electronic devices may emit vibrations or ultrasonic frequencies that are meant to deter snakes. Natural remedies might rely on scents or substances that snakes dislike. The effectiveness can vary based on the specific product and its active ingredients.
2. Snake Species: Some repellents might be more effective against certain species of snakes than others. What works to repel one species may not work as effectively for another.
3. Application and Environment: Proper application and coverage of the repellent in the intended area are crucial. Rain or environmental conditions can dilute or wash away chemical repellents, reducing their effectiveness. Additionally, the terrain, climate, and surrounding environment can impact how well the repellent works.
4. Habituation: Snakes, like many animals, can potentially become accustomed or habituated to certain repellents over time. If they don’t perceive the repellent as a significant threat or if they find alternate routes, they might bypass areas treated with repellents.

In general, while some snake repellents may have anecdotal success in deterring snakes temporarily or in specific circumstances, there’s limited scientific evidence supporting their consistent and long-term effectiveness. 

What Else Can You Do?

Professional snake handlers and researchers often rely on habitat modification, removing attractants (such as food sources or hiding spots), and physical barriers as more reliable methods to prevent snake encounters.

​A common problem amongst chickens in the backyard setting, is that chickens spill feed. Rodents from the wild, rats and mice in particular, come to scavenge up food items from chicken coops. Most times, snakes are after those rodents. 

The best solution is to only put out enough feed for your flock for the day in order to keep an environment free of spilled feed.

​Antivenom and Chickens

​Some studies  show that “chicken egg yolk antibodies were effective in neutralizing the lethality and several pharmacological effects of V. lebetina venom and could be used for developing effective antivenom.” – NIH

How fascinating is that? But it gets even better. All kinds of different animals are used to make effective antivenom around the world. Those made from chicken protein are shown to work more effectively than those made of mammals. 

Work in this field is continuously updating to better our chances at surviving snake envenomation.

Are Any Animals Immune to Snakes?

​Yes. Although we’ve already established that chickens are not immune to snake venom, it’s interesting that there are four mammals immune to snake venom:

• honey badger
• hedgehog
• mongoose
• Virginia opossum

You may or may not have these wild animals on your homestead. The only one that we have here in North Florida is the opossum, and this little fact makes us think twice about harassing them.  The tricky thing here is that opossum will also eat baby chicks and eggs. We just have to make sure that our coop is secured well at night.

Conclusion – Are Chickens Immune to Snake Venom

To answer the question are chickens immune to snake venom, I hope we’ve thoroughly explained that no, they are not. In order to properly protect your birds, we recommend keeping them in a secure chicken coop, clean up spilled feed, and get a couple of guinea hens. Hopefully, taking these steps will be enough to keep snakes from harming your laying ladies.

​Happy Homesteading!

Donna and her family have been homesteading for most of their 20+  years together in some shape or fashion. She currently lives on their 20 acre farm where they grow as much food as possible. What started as a just a few laying hens, has grown into large gardens, pastured poultry, pork, and lamb. They are continuously evolving their small farm to not suit their family’s needs, but also providing to their local community. Donna’s favorite part of the family farm is her self-built micro-dairy, where she gets to love on dairy cows while serving her local community. Milking, cheesemaking, and processing dairy have become the soul of their homestead and the center of their farm.
