I'm planning on using a brooder lamp to heat above the water, but they should be fine as long as the coop I is insulting, draft-free, and has good ventilation.Thank you so much, very helpful. I actually go out and talk to them (sounds crazy) and they recognize my voice and come running now. They are spoiled too, they love snacks, lol. Do u use heating lamps in the winter? Some people say to and othes not to , being new to this I can use all the help I can get. And light?
