Hi, I'm sure this has been answered, but when and how do we make the transition to living in the coop? Our 4 chicks (should I say, chickens) are pretty much fully feathered and spend a lot of their time outside already. We let them out during the day and bring them in at night. Our coop is finally done! (Yeah!) but it still gets chilly here at night - so we should probably continue to have the heat lamp in the coop, right? And do we slowly introduce them to the coop or just wish them luck as they spend their first night outside?!? I was debating having them outside (to play ) and then a few hours of dark in the coop and back into the house. Or am I being neurotic?
