Hmm. Good idea. I think I'm just going to leave the door open in the back from now on. My chicks go inside the coop at night on their own but it would be nice for them to be able to come and go as they please. I feel pretty secure with my run.Why do they need to stay in the coop for a couple of weeks? I'd imagine you might want to leave them in for a day or two, to get them used to sleeping in the coop, but beyond a few days it's not necessary. And, IMO, if your run is predator proof, why worry about where they sleep? I've had birds sleep outside for years and do just fine. Littles aren't likely to roost right off anyway, so if they sleep on the floor of the coop or the floor of the run, does it really matter?
