Last night Angel decided to take the girls into the 4' long covered community nest box (her favored nest for laying). It is nearly as big as the brooding area but no food or water. She likely moved them due in part to the fact that since she can't get out the little opening into the coop, she was tired of being the only chicken in the brooder area in the morning. Zorra did the same thing when the 2015s were a few weeks old. Except she took them to her favorite nest which is about 14" square. Not a lot of room for a big hen and growing kids.
I'm thinking one of the Columbian Wyandottes is a little roo. Nearly 4 weeks old, all the others have substantial tails, all wing feathers and feathers on their backs, still fuzz on their heads. This one has a stubbly little bit of tail, shoulder feathers not in yet and not a single feather on its back, all fuzz. So while I was expecting 7 new layers, with the Barnevelder kicking off (for whatever reason) and in all likelihood one of the others being a roo, I'm down to 5 new future layers.
