The weather has been so mild I put them in their grow up pen. They had been off heat for a few days, then out they went. They are doing great! But I MISS them being in the back room where I watch TV. I'm getting new chicks in about 3 weeks so I'll be ok. I bought them a prefab coop they sell at TSC. It was on sale so I figure it would be ok for a grow up pen, not a real coop. They love the extra room. I have to catch them one by one to put them in the sleeping area at night. I think they will figure it out soon. I have a light in there but they don't get it yet. I knew it would be that way. This weekend I will be moving the prefab next to the real chicken coop so they can see each other. Then after a week or so I will let them free range together. I plan on making a little door on the prefab so only the little chickens can fit through. The 6 week old chicks are bantams and the other chickens are LF. Once I decide On what I'm keeping I will either put them all in one coop or build another one. Just wanted to share my chick progress.
