I needed to get the poults out of the brooder so I let the Blue Slate hen and her 5 three week old poults out of the grow out pen. After I got the poults out of the brooder, I found out she was out beating up on another hen. During the fight, I took the three week old poults and put them in with the others in the grow out pen.
Later the hen was fussing wanting her adoptees back and keeping all of the chickens out of the coop. I let her back into the grow out pen and everything finally calmed down. She now has 28 adoptees instead of 5.
