What is Too Cold for the Chicken Coop?

I can't help much, but the chickens can survive surprisingly low temperatures. The biggest winter problem that we deal with is keeping the water thawed. We put a heat lamp on the waterer, and that just keeps it thawed out. We don't do anything more than that for our chickens, but our coops are pretty draft-free. The chickens huddle close together on the roost to keep warm. I'm sure your winters are quite a bit colder than they are here in central IL. Maybe somebody in a climate closer to yours can help more.

 

Close up the holes,gaps between boards and other places the wind can blow through. Chickens can stand a lot of cold but it's the drafts that can kill them. There are some members here from Alaska that keep chickens and have few problems with the cold.

I say eliminate the drafts. That will be your most important way of helping your birds.

 

look in the past-posts about winter ventilation. thats what i did and i'm a little north of you.

 

You mentioned that the shed is "breezy," which will be your biggest issue. You'll want to make sure it's draft free, no breezes/moving air. As was already mentioned, that could kill your birds. That being said, you do want ventilation, but you want it up high, well above the birds roosting area, so that icy wind can't blow on them. Really pile up your bedding. Depending on how many birds you have compared to the size of your coop, you may want to consider a huddle box for them...
Many opt for heated waterers rather than supplemental heat (and if your roof isn't insulated, any heat will go right through anyhow), as it really gets old breaking out iced and refilling with warm water 2 or 3 times a day. Plus a heated waterer would create a tiny bit of warmth.

 

please look up "patandchickens" big 'ol ventilation page...... and I was also told as long as there's no draft and ventilation is correct, they can handle up to 20 below

 

here it is..

I agree - get rid of the drafts, pile up the bedding. I don't heat my coop and even my serama hen survived 3 Iowa winters just fine. Make sure the boards are flat side up - the chickens will roost with their bodies covering their feet to keep them warm. We just added some birds to our flock to make sure there was plenty of body heat to go around. I have only had one problem bird - my black copper maran roo lost the spikes on his comb last year and some of his toes. He kept walking in the water and incasing his feet in ice. He spent a good portion of the winter inside.

 

In addition to my ventilation page you might also want to look at my "cold coop" page, link in .sig below, since it addresses exactly these sorts of issues

Good luck, have fun,
