No matter how experienced you are in raising chickens, as the mercury begins to drop you might start second-guessing yourself and wondering, “how cold is too cold for chickens?”
This is a concern raised by chicken keepers everywhere, but especially those who live in cold, unforgiving climates. Luckily, chickens are pretty hardy creatures and can withstand the bitter cold much better than you might think.
There are some conditions you’ll want to keep in mind, of course. For example, some chicken breeds aren’t as adept at withstanding the cold as others. There are certain precautions you can take, too, to help your birds shed the cold and continue to stay healthy.
Here’s what you need to know.
How Cold is Too Cold For Your Chickens?
Your chickens are tougher than you might think. In fact, even though they aren’t wearing big, puffy coats like us in the wintertime, they have natural defenses against the cold that can keep them warm.
Chickens have several types of feathers. There are wispy feathers and plumage feathers. The plumage feathers are the colored ones that are easiest to see when you quickly glance at your birds. The wispy feathers are similar to down in that they stick tightly to the skin and keep chickens warm, essentially creating an airtight barrier.
Not only that, but chickens also have high metabolisms. They have higher resting temperatures than we do. While a human stays around 98 degrees, chickens are closer to 105 to 109 degrees Fahrenheit. Plus, their hearts beat a lot faster than hours – up to 400 beats per minute. This helps your birds stay warm even when you’re running toward the woodstove.
Depending on the breed, most chickens can survive inside an unheated, uninsulated coop at temperatures that are well below freezing. There’s no hard and fast number on how cold is too cold for chickens, since there are so many variables that affect a chicken’s cold hardiness. Here are a few.
Some chicken breeds are naturally better at shaking the cold than others. Usually, chickens that are heavy and large will be better at staying warm. Some of the best breeds for winter weather include:
- Barred Rocks
- Salmon Faverolles
- New Hampshire Reds
- Rhode Island Reds
- Jersey Giants
- Barred Rocks
Cold-hardy chicken breeds are those that have high body fat and don’t have any areas of exposed skin. Similarly, frizzles (or curly feathers) along with feathered feet can make chickens more sensitive to the cold. Therefore, you’ll want to avoid breeds like Silkies, which don’t dry out easily in cold, wet weather.
It can be tough to determine how cold your chickens can get because it’s not just the temperature you’ll need to keep an eye on. In fact, chickens tend to be more sensitive to humidity and moisture than actual cold.
In almost all cases, chickens will handle cold, dry weather better than cold, wet weather. This is especially true if your coop has a tendency to hold moisture. A driving wind can also lower the ambient temperature and make it more difficult for your chickens to stay warm, too.
Age and Life Stage
Finally, consider how old your chickens are (and whether they are in any particular stage of life that would make them more sensitive to the cold). For example, young birds and those who are molting may not have as many feathers to withstand the cold. You’ll need to take a few extra steps to keep them warmer during unusually cold weather.
How to Help Your Chickens Stay Warm
Avoid a Heater
The number one tip to remember when helping your chickens stay warm is that nine times out of ten, they do not need a heater.
Heaters are problematic for several reasons. First, with all that bedding, you’re inviting a fire. Chickens do not need a heater because they will huddle up together at night to stay warm. A well-ventilated coop with plenty of fresh bedding (and a proper ratio of roost bars to chickens) is all your birds need.
Another issue with a heater is that, if the power goes out (or when your chickens venture outside) they will suffer from the fluctuation in temperature. Your chickens don’t have a hard time acclimating to the cold when it’s always cold out -but when they can’t adjust to sudden swings, that’s when health problems arise.
As long as your coop is well-ventilated, it doesn’t need to be insulated, either. In fact, too much insulation can be detrimental because it makes it difficult for moisture to escape. Believe it or not, chickens release a lot of moisture when they breathe, so a too-tight coop can lead to moisture build-up in the coop. This will chill your chickens much faster than the cold weather will.
Try Deep Litter
Deep litter is a method of bedding that allows bedding material and chicken manure to build up over the year. By winter, you’ll have a foot or more of composting material on the floor of the coop. As you probably already know if you have a compost bin, the composting bedding will give off heat and will warm the coop naturally. You can clean it out come spring.
Feed at Night
Feed your chickens at night during particularly cold spells. If you give them high-energy foods, like cracked corn, they’ll stay warmer overnight as their stomachs work to digest the food.
Keep Them Occupied
Make sure your chickens are kept entertained during the day – the activity will boost their metabolisms even further, helping them stay warm. Ideally, you should let your chickens out of the coop to roam around during the day, but you might find that, when it’s super snowy, your chickens don’t want to venture outside (although the cold does not bother them, they aren’t fond of walking in heavy snowpack).
If your chickens can’t be encouraged to go outside, consider hanging a head of cabbage by some twine in the coop. This will entertain your chickens on the darkest days of winter.
Harness the Power of the Sun
Consider adding a sunroom to your coop. You can do this in several ways.
A coop with plenty of natural lighting is best, as this will help warm the coop during the day (and the coop will hang on to some heat at night, too). You can also build a cold frame-style addition to your coop or run by covering a section with clear plastic. This will give your chickens somewhere to relax in the sun during the day – and as a side bonus, it will usually stay free of snow, too.
Don’t Forget the Roosts
Chickens don’t need a heater! Again, they just need a place to roost. The key to warm chickens is a good roost set-up. The roosts will not only keep chickens off the cold ground (ideally, two to three feet off the ground) but they will also allow the birds to huddle together. When chickens are able to roost properly, they’ll be able to use their feathers and bodies to cover up their cold-sensitive feet, too.
Guard Against Frostbite
As long as your coop is well-ventilated, you shouldn’t have to worry about frostbite. However, in the coldest winter climates, some chicken breeds who have large wattles and combs may develop frostbite. Luckily, it’s nothing serious – it will just cause some discoloration on these parts of your birds.
However, you can protect against it by dabbing some petroleum jelly on the wattles and combs. It forms a moisture-resistant barrier.
Plan for Laying Declines
Your hens’ laying patterns will naturally decline during the winter – that is only to be expected. It is caused not only by a reduction in natural daylight hours but also the fact that your chickens are spending more calories on staying warm than they are on producing eggs.
If you’re really concerned about a drop in egg production, you can add a light to the coop. This is really only for your benefit, though – the chickens don’t necessarily need it.
Water is Essential
Your chickens will naturally eat a bit more during the winter months, since they don’t have access to fresh forage and they need to eat just to stay warm, too. Make sure they have consistent access to feed and remember – without water, the feed is pointless.
One of the biggest challenges of raising chickens during the winter is having to deal with frozen waterers. Consider using waterers with heated bases to help prevent the waterers from freezing. Don’t forget to refill often – eight chickens need at least a gallon of water per day.
Chickens: They’re More Cold-Hardy Than You Think!
When it comes to raising chickens during the winter, you’ve got to give them some credit – they’re tougher than you might think! While there will be some extra work involved when you are raising chickens during the winter, ultimately, the stress will be on you and not on them. Collect eggs a few more times during the day and make sure the waterers stay thawed out. Otherwise, your chickens will hardly even know that it’s winter outside!
