I have 2 silkies and 4 big chickens. I need to know if I have to heat the coop. We all know how the winters can get in Wisconsin. We did insulate the whole coop and we also put up plastic to help. Iv read some stuff some people say yes and some say no. They say if you do it can make them sick and also they get frostbite. I just want what is best for my babies... . I'm kinda new with this chicken stuff..
