Today mama flew down out of the coop and called to her kids and they followed so they're all out of the little coop.They didn't leave the barn though and hung out in the common coop all day. We put water and baby food down on the floor and everyone seemed happy to have more room to run around. The other hens would come in and lay their eggs and there was no fighting or fussing. The other hens seem to like the babies fine. I'm posting a picture of them. They are three weeks old today.
