How To Prevent Frostbite During Winter?

How To Prevent Frostbite During Winter Blog Cover

During these cold winter months, your girls have a lot more to worry about than lack of daylight! One of the biggest problems which can occur is frostbite.

It was Ben Franklin that said ‘an ounce of prevention is better than a pound of cure’.

He may not have been talking about chickens at the time, but he was certainly right about frostbite!

The prevention of frostbite is relatively simple and will keep your birds healthy and content.

Preventing it in the first place is a lot less work for you and better for your flock, although occasionally, there will always be chickens that get frostbitten, despite your best efforts.

First, we’re going to look at how chickens get frostbite, and then we will look at some of the easiest ways to treat and prevent frostbite.

Please read our Definitive Guide To Keeping Chickens In Winter, for more advice about raising chickens during the winter months.

What is Frostbite?

For the core body of a mammal/bird to stay warm in colder climates, the body decreases the amount of blood flow to the extremities.

In humans, it’s fingers, toes, ears, and noses. In chickens, it’s combs, wattles, and feet.

With the decreased blood flow, the tissues cool down; if they get cold enough, the fluid in and around the cells freezes.

This freezing can cause cell death, disrupt the blood supply, and create small blood clots in the affected area.

There are three levels of frostbite severity:

  • 1st degree: tissue irritation; the skin will be soft, white, and warm, often referred to as ‘frostnip’.
  • 2nd degree: hard, white skin, the skin has a ‘frozen chicken’ feel (no pun intended), swelling, blisters, loss of sensation, usually no residual major damage.
  • 3rd degree: area will feel hard & waxy, swollen, with blackening of tissue, and necrosis. Permanent damage to tissue and nerves has occurred.

Frostbite causes pain, and decreased mobility/disfigurement. It can temporarily cause low sperm count in roosters and decreased egg production in hens.

What Causes Frostbite?

Surprisingly, it’s not just the cold- its moisture and the cold which causes frostbite. It can be caused by a variety of things in combination: low temperature, wind chill, length of exposure, lack of shelter, moisture, high altitude and decreased circulation in older birds.

Many of these things can be prevented or adjusted- more on that later!

Frostbitten Chicken Symptoms

If you think you have a frostbitten chicken, here are some signs that you should look out for:

  • Color change in the area – white/gray/yellow/blue
  • Swelling
  • Area may initially feel warm to the touch, later it can be cold and hard
  • Blisters
  • Limping
  • Blackened tissue
  • Loss of appetite
  • Listless (in very severe cases)

Frostbite Treatment for Chickens

If you think your hen has already got frostbite, follow this section to learn how to treat frostbite effectively.

This section is divided into ‘dos’ and ‘don’ts’. I have tried to give a brief explanation of each with the entry.

What To Do

Immediately move the frostbitten bird to a warmer location for treatment.

Gradually warm the affected area. The circulation needs to return to the area slowly. Heating the area rapidly will cause more tissue damage. Start with a lukewarm washcloth slowly working up to normal temperature. This may take some time.

Make sure the bird is drinking, especially in the case of affected wattles. You can add vitamins/electrolytes to the water to aid with the healing process.

Soak the feet in lukewarm water with Epsom salts one or two times/day for a week, longer if necessary. This will encourage the return of circulation to the feet. The process may take several weeks if the frostbite is severe enough.

During their recovery you need to carefully monitor their dietary intake- they need to eat plenty of food during this period.

Finally, watch all affected areas closely for signs of infection or necrosis. If either occurs you should consult with a veterinarian immediately.

What Not To Do

You shouldn’t do certain things under any circumstances when treating frostbite.

Don’t rub the frostbitten area.

This won’t help and will be painful for the bird.

Don’t use direct heat such as a hair dryer or heat light- it can cause further tissue damage.

Do not break open any blisters. The fluid inside is protective and opening them gives a potential entry source for infection.

Do not ‘trim’ blackened areas unless they are infected. You should really consult a veterinarian at this point.

How To Prevent Frostbite In Chickens

Here we return to Ben Franklin! If you can prevent frostbite in the first place, you will save yourself a lot of work and save your hens from suffering.

Earlier, we mentioned some of the reasons frostbite occurs. Here we will deal with them individually to see how we can reduce the chances that your rooster or hen will get frostbite.

Low Temperature

Not much you can do about this in general.

Chickens apparently don’t start to feel ‘cold’ until the temperature hits -20F who knew?

They can tolerate low temperatures very well as long as they have a draft-free area to shelter in.

We have discussed heating the coop in previous articles, but I still maintain that in most cases it isn’t necessary. If you hang a thermometer inside the coop, it will usually read 32-40F.

How come?

Well, a typical hen generates around 10 watts of heat, so multiply that by the number of birds in the house to give you a ‘lightbulb’ number.

Example: 10 hens each producing 10 watts = 100w lightbulb!

If you have the desire to heat the coop – please use an oil-filled radiator or wall unit heater, not a heat lamp for safety sake.


Respiration and poop both contain large amounts of moisture.

As long as your coop is well ventilated, most of the moisture should be expelled from the coop.

If you are concerned about frostbite, you can put Vaseline or a similar oil based cream on the wattles and combs.

Vaseline does not prevent frostbite. It forms a barrier to moisture on the exposed areas.

Wind Chill

The wind chill increases the rate of heat loss from the body. The air movement disrupts the ‘boundary’ layer of air around a body, so more heat is lost.

Wind chill can be extremely dangerous.

The birds need to have a wind free area. You can cover their runs with tarps or plastic sheeting to prevent the wind from whipping through the area.

If your coops have gaps/holes, they need to be plugged up to prevent the chilly breeze getting in!

Length of Exposure

How long was the bird outside? Your hens should always have somewhere relatively warm and draft free to retreat to. Also, walking on snow will chill their feet down considerably.

Clearing an area of snow and throwing some straw onto the cold ground will help protect their feet a little whilst the hens are getting some exercise.

Lack of Shelter

they should always have somewhere covered and dry to hang around in.

If the hens choose to go outside in the cold for short periods, that’s fine, but they should never be thrown out of the coop for some fresh air.

Some say their birds ‘get into mischief’ if they are inside all day.

This can be combatted by providing enough room for them in the first place; the more room the birds have, the less ‘mischief’ you will see.

You can also provide diversion therapy such as tetherball or a ‘rolling’ treat dispenser.

Decreased circulation

in older hens/roosters, this can be problematic in the colder months. Simply keep a close eye on your birds and any that seem to have a problem with the cold, and try to keep them out of the weather.

Despite our best efforts, a bird will occasionally suffer from frostbite.

Usually, it’s a mild case, but sometimes they lose combs, wattles or feet!

Although comb and wattle loss is unsightly, it is manageable. Remember that a bird ‘sweats’ through its comb, so temperature regulation is affected, that’s something to be aware of in the heat of summer.

Since certain breeds of chickens do better in cold climates, it is worthwhile to do your research if you know you’ll need a breed that can withstand extreme temperatures.

For example, roosters with tall combs, called single comb, have an increased risk of frostbite because the comb is not situated close to the rooster’s head.

The closer to the head, the more warmth is retained.

So, instead of Welsummers, look for breeds with short combs like Dominiques or Silkies.

Some chicken keepers protect their tall-combed birds with things like Vaseline, which is thought to prevent frostbite in certain situations.

However, if you apply any type of product directly to your chicken’s comb, make sure it will not freeze…this can cause even more problems.

It’s something to look into if you’re experiencing a cold snap in your region.

How To Prevent Frostbite in Chickens: Summary

Winter is coming- there is no changing that as much as we might wish. Now you know how to prevent frostbite in chickens.

Frostbite can cause long-lasting, permanent damage to your flock, so it’s crucial that you prepare your chickens and coop for the winter.

Follow the steps outlined in the prevention section above and your girls will be fine this winter!

Much of the work of protecting runs with tarps etc. can be done in the slightly warmer months of October and November.

Winter time puts extra strain on us all – from carrying buckets of water to the coop to clearing snow for the flock. It also stresses the hens too.

The day-to-day activities they are accustomed to – hunting for bugs, nibbling grass, etc. are suddenly gone. It’s up to us to keep them healthy and occupied during these cold days, plus warm and comfortable at night.

If you have any other ideas for keeping your hens warm and busy during the winter months let us know, we love to hear from you!

  1. Thanks for all your great advice.
    My chickens have a cough and I noticed snot coming from from one of my girls nose what can I do

  2. I was blessed with a very sweet Buff Orpington Rooster this past fall. He sits on our laps and loves to be held. Unfortunately, he’s just showing signs of frost bite on his comb and waddle. In doing much praying, research and reading many blogs I’ve discovered the problem is with my coop.
    I have a very well insulated coop and no drafts. But I don’t have venting at the top and never understood it till now. What I’ve learned is:
    DRAFT means enough air movement to fluff the chickens feathers so they can’t keep warm. VENTILATION means air movement at the top of the coop for heat/moisture to escape. What I didn’t know was the heat from their poo and breathing carries the moisture to the top of the coop and out the vents. It’s not up to us to keep the chickens warm. They already have that covered by fluffing out their feathers and huddling together. So it’s time for me to go out and cut two vents in the upper part of my walls to allow air flow. If anyone has any comments on this, I’d really like to hear from you. I don’t want to loose my little buddy Rooster. Thank you and God bless you.
