Prepare Your Chickens for Northern Winters

I’ve loved seeing the backyard chicken community grow over the years- and especially this past year! So many new chicken owners; I lovingly refer to us as “chicken tenders”. So it seemed like a good time to gather my thoughts for an overview on getting your hens ready for winter. This article focuses on smaller backyard flocks because this is what I’ve had the most experience with, and what most newbies start with.

For us backyard chicken tenders there are specific city rules and responsibilities. I go over some of those and other local chicken keeping resources in my post, Chickens in the Hood. I also bear my soul in the sobering blog, Fresh Eggs to Chicken Soup, about when we decided to cull a flock of our hens a few years back.

Transitioning to Winter

Transitioning hens to winter can be smooth when you follow a few simple steps… Yes, even if we’re rushing after a freakishly early snowstorm and weeks earlier than normal! Just pat yourself on the back that you’ve taken a step to lessen your reliance on corporate food systems and get a good pair of gloves for winter chores.

Keeping chickens over the winter really comes down to keeping them dry and out of the wind along with giving them plenty of food and water. This should give you happy hens down to -20°F. But, let’s get real- nothing is happy colder than that. Like at any other time of year, being with your hens and knowing their routines is your best offense.

If there’s one thing you get out of this article, let it be that chickens are tough birds! While cold by itself can harm chickens, the thing that can really harm your hens is that sneaky combination of damp + cold together which causes frost bite faster. We’ll cover this in depth later on. For now, we’ll go over three area; the coop, the hens, food + water,
but of course they all intermix along the way.

The Coop

Coops come in all shapes and sizes. If you ever need coop inspiration check out Egg|Plant Urban Farm Supply’s annual “Chicken Coop Tour”. So, what might work in one yard/coop/flock may not in another.  I’ll give basic ideas that can be used to fit your chicken coop no matter the shape or size.

Coops need ventilation, but not wind. This can seem antithetical. Think of it this way- we leave our coops uninsulated but cover the 6’X6’ mesh window in winter. Heat, and most importantly moisture, will escape between the roof trusses this way.

Once upon a time, when we were chicken newbies, we insulated our coop. Airtight. Too well. Luckily, that was during the warmer winters of a decade ago. But, even with lows around 20°F I noticed a LOT of humidity in that coop.

Poop in the Coop

As air gets colder it loses its ability to hold moisture. Add to that, the fact that chicken poop also contains all the urate (what humans would pee separately) and you’ve got a high percentage of water to deal with. The urate is also where that ammonia smell comes from. Most people keep a minimum of 4-6 hens in a relatively small space in urban/suburban settings.

So, let’s imagine it’s one of those -10F mornings and they’ve been in there all night (PS- chickens poop in their sleep) cooped up… then they go outside with colder temps, and maybe some wind chill, the dampness surrounding their combs quickly becomes frozen and you’ve got a hen with frostbite in a few minutes.

With colder but dry combs as the hens come out of the coop, they’re much less likely to get frostbite. So, you can see how important good ventilation becomes!

One of the basics is keeping chickens dry – and if you didn’t notice over your honey-moon period of chicken keeping over the summer- chickens release a LOT of poop, around 1/3  – ½ pound per day depending on the breed. That $#% needs somewhere to escape! If you’re really interested in the chicken digestive tract, and not squeamish about lots of chicken poop pictures, Check out Fresh Eggs Daily’s post: All About Chicken Poop.

Here’s where I’ll give a big Shout out to the “Poop Plate”. This is any board (or piece of metal for really easy scraping) that you put below the roosts to catch poop, because remember chickens poop in their sleep! This makes cleaning the coop so much easier in winter.

Lots of northern chicken tenders enclose their chicken run to some extent. I usually tack on an old clear plastic shower curtain or some garden poly. This lets light in, but keeps wind and snow out. It can even get a little like a greenhouse on calm, sunny days. I tend to wrap just two sides, because the whole idea is to have them outside, and it’s only on the coldest days that I’ll confine them into either the inner coop, or the coop  + run.

How Cold is Too Cold?

As always, I think watching your chickens and see where they hang out is your best chance for raising happy hens. There’s no hard and fast rule to how cold chickens can survive because it depends on the breed, any wind and relative humidity. But generally, if it’s not getting above 0°F I don’t let mine out. If it’s only going to get to single digits, I tend to let them out in the afternoon- and keep them in the run so they don’t get so involved in scratching they forget how cold they are. This usually only happens a handful of times every winter.

We also try to have a solid covering in place for winter over the run, this really helps keep snow out. This not only makes it nicer for the girls in winter, but also in spring when everything melts having snowpack underfoot becomes one HUGE mess! Ask me how I know 😉 *We usually have small run areas, 4’X6” or 3’X8’.

I know some of our chickens hated going into the snow and would only venture out after others had forged a path. Others would fly into the middle of a snowy backyard without a care. Both are normal. Both are OK.

Hay There!

Add more hay. We use hay in our garden to insulate plants, and in our coop to insulate the chickens. We’ll be trying the deep litter method again this winter. This is the practice of adding more hay to the spent bedding throughout the winter and letting it decompose in place. While this sounds gross, it’s actually pretty cool, *if* you can keep the moisture down.  The idea is come spring, you’ll have some finished (or nearly finished) compost for the garden. The decomposing hay and chicken poop give off heat, a nice bonus during our cold winters.

You’ll also want to make sure that ALL the chickens can comfortably fit on a roost up off the ground as sleeping on the floor invites disease and is colder. They also appreciate a roost off the ground outside in winter!

Coop Heaters

A point of contention for some chicken tenders is whether to heat the coop. Heating the coop can keep your chickens from getting acclimated to the winter temps and they’ll end up staying inside more; getting less fresh air and less chance to move around and forage. It can also pose a fire hazard if a cord is near or on the ground. You may think you’ve got the cord tucked away, but seriously chickens can be worse than rock stars at an after party.

We never heated our coops until a friend gave us this heater with her hens that we added to our flock. I will say they serve a purpose. It goes back to we do use a timed light bulb to add light hours to their days. Adding light keeps chickens laying eggs more consistently. Chickens slow down and speed back up their laying with the seasons, unless given a little supplemental light. We usually set it to go off an hour or two before normal sunrise, starting around November, going until February. I’d suggest starting earlier in the morning rather than at night, because a light that suddenly goes off might catch a hen off guard. This means a hen could spend the night on the ground and will end up more stressed out as a result.

The Hens

It never fails, I always have that one hen that starts molting about the time the temperature dips. I take care to give hens molting in cold weather extra dry spaces, as girls without feathers around their necks or under wings are the only hens that might have a hard time staying warm enough.

In general chickens are very capable of keeping themselves warm. While they aren’t exactly like wild birds (think chickadees and cardinals) remember they are birds. Some birds hang out in Minnesota (and even colder places!) all winter long. That said, cold tolerance varies with breed; larger breeds being the best in cold climates mostly due to body mass.

Frost Bite + Comb Care

Frost bite can harm our hens quickly and permanently. It can happen within a few minutes but is avoidable. The bigger, thinner and more ridged the comb, the easier it is to get frostbite. I’ll give a shout out to pea combs here. Those tiny, barely-there combs hardly ever get frost bite because they have good blood supply and are so close to the head. Big floppy combs, while adorable will need some extra care in a typical Minnesota winter.

When it gets “January Cold”, as my kids call it- I bring out the small jar of coconut oil and place it above the wood stove to have at the ready. Coating the combs and wattles creates a waterproof barrier between the skin and the cold. Not very insulating, but it keeps the wet off. And remember Cold + Moisture causes frostbite faster on combs. Have I pounded that in enough?

Even so – I like to push the limits and let my girls outside as much as possible, and mine have gotten frostbite. You’ll first see white tips on their combs. Then they will turn black. Really bad cases the affected parts will fall off. This is very painful for your hens, and we try to avoid this at all costs.

Food + Water

As always, give your hens plentiful feed, indoors and outdoors, as long as it can be kept dry. I tend to up their protein during the transition time too, this especially helps that one hen who’s always molting. The protein can be ground up nuts, leftover beans, or a few extra meal worms. I also make up some fun winter treats like garland from produce past its prime; like apples, kale/broccoli leaves, cabbages, and even cranberries. Another favorite treat to feed inside the coop (because it is dry and full of extra energy for when it is really cold and they are stuck inside the coop) is the “Flock Block”

Some people put dog waterers inside, and this just seems like a mess waiting to happen. If you have a smaller backyard coop, please do not put an open topped heated dog waterer inside your coop. Chickens will walk through, poop in, and just get wet (wet = cold) with open water inside a coop.

We use a simple heating pad under the regular waterer which is raised up off the ground. This keeps the water clean, and thawed on all but the coldest of mornings. We just inherited a heated waterer unit and plan on using this outside the coop for an additional water source during the winter to replace the extra water dishes I fill up in the summer.

I will typically add a tablespoon or two of Apple Cider Vinegar to their water once a week just to help their systems. ACV is one of my secret winter weapons to keeping my flock healthy.

I also keep greens around for them for calcium and for something to work at in the winter. I am a huge fan of brassica leaves for my hens. This gives them a great boost of calcium, plus so many other nutrients. It also keeps them busy. I toss over the lower/larger broccoli, cauliflower, beet and kale leaves all summer. I purposefully leave some brassica plants standing in the garden as long as I can to break off leaves and parcel them out to the girls. Later in winter/early spring they get leaves I’ve frozen for them.

Keep it FUN

Adding some herbs, like thyme, mints, lemon balm or oregano to their bedding isn’t necessary, but is a nice extra line of defense. Thyme and oregano have serious herbal benefits with anti-inflammatory, antimicrobial, and antioxidant effects. I add herbs to their bedding, which they scratch in too, to give them a leg up on any congestion issues they might get. *I use thyme tea to sooth my own sore throats and coughs too.

For a real treat, we’ll string up a cabbage, or set out a chicken treat stick. We plan to give them some ‘garland’ for a Christmas treat – and if you missed it, I just presented my girls with a pumpkin Rooster- ha! I wanted to leave with you a reminder that keeping chickens is FUN!

I’ve got some video on winter prep under my “Chicken TV” Stories on Instagram, if you’re looking for visual how to’s!

I hope this helps prepare you for a FUN winter of chicken keeping in the bold north! Let me know if you have other tips and tricks for keeping your hens happy all winter long!
