Very cute & a great idea. Our 1st coop we built last spring is insulated well & has electricity, we have turned that into our brooder & juvenile coop. It works great, I have 6 wk olds, 4 wk olds & 2 day old chicks out there. The ambient temp of the room is 50-60 and then the babies chicks have their heat plate for warming up under. I have found they feather out much faster & get acclimated to the outside temps faster this way. In addition I don't have all the chicks in my basement reeking having to my health.
