What Is A Chicken Snake? [The Surprising Answer!]

The Name “Chicken Snake” Explained

If you live in the southern United States, you have probably heard someone mention a “chicken snake.” It is a common folk name that gets used a lot in rural areas, but it is not an actual species. The term “chicken snake” is an informal name applied to several different snake species that are known for raiding chicken coops to eat eggs and occasionally small chicks.

The name tells you more about the snake’s behavior than its identity. Any snake that shows up around poultry and helps itself to a meal of eggs can earn the chicken snake label from farmers and homesteaders. Understanding which species are most commonly called chicken snakes and whether they are actually a threat to your flock can help you respond appropriately when you find one in your coop.

Which Snakes Are Called Chicken Snakes?

The most common species referred to as chicken snakes are rat snakes, particularly the black rat snake (also called the Eastern rat snake or black snake) and the Texas rat snake. These are large, non venomous snakes that commonly reach 5 to 7 feet and are excellent climbers. They are found throughout the eastern and central United States and are frequently encountered around barns, sheds, and chicken coops.

Corn snakes, which are also in the rat snake family, sometimes earn the chicken snake name as well. In some areas, king snakes, bull snakes, and even coach whip snakes are called chicken snakes if they are found near poultry.

What all these species have in common is that they are large enough to swallow chicken eggs and skilled enough climbers to get into coops and nesting boxes. They are all non venomous constrictors that pose no danger to humans.

Are Chicken Snakes Dangerous?

Chicken snakes are not dangerous to people. They are non venomous and their bites, while they can hurt, are not medically significant. Most rat snakes will try to flee rather than bite, though they may put on a defensive display by vibrating their tail, musking, or striking if they feel cornered.

For adult chickens, chicken snakes are generally not a threat. Full grown hens and roosters are too large for these snakes to eat. The real concern is eggs and very small chicks. A large rat snake can easily swallow multiple chicken eggs in a single visit, which can be frustrating if you are relying on your flock for eggs.

Young chicks that are still very small may also be at risk, particularly in the first week or two after hatching. Once chicks grow past the size that a snake can swallow, they are no longer in danger.

Why Chicken Snakes Are Actually Beneficial

Before you grab a shovel and head for the coop, consider that the snake that is eating your eggs is also eating the mice and rats that would otherwise be getting into your feed, spreading disease, and chewing through equipment. Rat snakes are some of the most effective rodent control agents in nature, and having them around your property provides significant benefits.

A single adult rat snake can eat dozens of mice and rats per year. Without these snakes, rodent populations around farms and homesteads would be much higher, leading to more damage to stored grain, feed, and equipment. Many experienced chicken keepers view rat snakes as a net positive despite the occasional lost egg.

Killing chicken snakes often leads to increased rodent problems, which can actually cause more damage to your flock than the snakes ever would. Rats are known to kill chicks, steal eggs, and spread diseases that can devastate an entire flock.

How to Keep Snakes Out of the Chicken Coop

The most effective way to deal with chicken snakes is to make your coop snake proof rather than trying to eliminate the snakes themselves. Start by sealing any gaps or holes larger than a quarter of an inch. Remember that snakes can squeeze through surprisingly small openings, and if a mouse can get in, a snake can follow.

Use hardware cloth (half inch mesh) instead of chicken wire for enclosures. Regular chicken wire has gaps large enough for snakes to pass through easily. Hardware cloth keeps snakes out while still allowing good ventilation.

Collect eggs frequently, ideally twice a day. If there are no eggs sitting in the nesting boxes, there is less incentive for a snake to visit. Some chicken keepers also use ceramic or wooden fake eggs to frustrate snakes that do get in, since the snake will try to eat the fake egg and eventually give up and leave.

Keeping the area around your coop clear of debris, tall grass, and woodpiles removes hiding spots that snakes use when approaching the coop. A clean, open perimeter around your chicken run makes it harder for snakes to approach undetected.

What to Do If You Find a Snake in Your Coop

If you find a snake in your chicken coop, stay calm. Remember that the most commonly encountered “chicken snakes” are harmless to you. If you are comfortable doing so, you can gently guide the snake out using a long stick or broom. You can also simply leave the coop door open and give the snake time to leave on its own.

If you prefer, you can carefully relocate the snake to another part of your property where it can continue eating rodents without bothering your chickens. Use a large bucket or trash can with a lid to safely transport it a few hundred yards away. For more information about common snake species, check out our guide to popular pet snake breeds.
