If you live in an area that has bad winters you will have to deal with chicken frost bite. You will either deal with it as a preventative measure or taking care of wounded birds. I’ll be honest I thought my first winter I did a good job of insulating and keeping the birds fairly warm. However; the moisture is where the problems came in. Insulating too much cant be a bad thing. The worst thing for birds in the winter is moisture. So two things I have changed is not insulating and heating my coop as much, also rubbing Bag Balm on the combs and wattles. So I hope this helps you with your birds this winter.
