I have four six week old BR's and I need to get them out of my dining room. My husband is finishing up their coop today and I ready a lot of the threads on when is best to move them and about temperature and such but I just want to make sure that they're going to be alright. We can't put a light outside in the coop as we don't have electrical out there. And forgive me for being Canadian but the temperature here is (if my math skills don't fail me) 75ish during the day and about 45ish at night. They're going to alright, right?
