it's pretty cold here (about 5) with a really stiff north wind of about 20 mph. the birds don't want to come out of the coop, and i can't blame them. i don't want to go outside either. their water and feed are inside the coop. i gave them some BOSS and scratch earlier for a little extra "punch" to keep them warm. do you guys do anything else besides those two to give your birds a better chance at keeping warm?
