I live in Indiana. Winters here are completely unpredictable. Last winter was brutally cold and very damp. I lost 6 chickens despite running heat lamps constantly. It was heartbreaking. My boys became interested in showing them in 4H, and guess who fell in love with them!?!! I have Sebrights and D'Uccles. If we had done proper research, we would have gotten a heartier breed, but for some reason my boys were infatuated with the Sebrights. The D'Uccle was thrown in as the extra, and then we acquired a few more after falling in love with their sweet temperment. As for the greenhouse, I am only wanting it for winter...not summer. I am so afraid of the coming winter and having to deal with the cold again. I've got to make something work for the few birds I have left without spending a fortune. I really appreciate the advice.
