Help! I recently moved my 5 bantam chicks out to the "grower" coop (ultimately will become my roo' coop) with my two grown sebright hens and today one baby OEGB hen was attacked by the adults. She's sleeping on my lap now in a little towel, pretty pecked up all over but I think she will be OK. I had set the chicks up in a pen adjacent to the adult hens for a week to get them used to each other, then let them all run around in a very large area (20' x 40') together for a few days before moving everyone, adults and chicks, into the "grower" coop about a week ago. It measures 84 in. x 42 in. x 57 in., and they get time to free range every day under supervision of my german shepherd. They've been fine, though the two adults have been a little bossy with the babies, but overall tolerant and they all sleep in a pile together without incident. What happened? What do I do? I am worried if this happens again when I am not home to intervene they will kill one of the babies. I am planning to keep the injured OEGB separate until she fully recovers. I am ordering another coop for her to stay in on my deck, as my "ER" coop is currently being used as a brooder box for two tiny pied guinea keets... ughhhhh What did I do wrong here, what can I do to remedy this? I have a much larger coop/run combo thing coming in 2 months, 6 x 12' run, hopefully the extra room will keep everyone happy? But until then...?
