One exsisting hen in coop - added 9 - 5 week olds two weeks ago - decided to add 2 more night before last. They came from the same brooder as the previous 9, but apparently they have forgotten them already. They are picking on both of them, but one is so terrified she won't come off the waterer but for a few seconds to try and get food. I also removed the likely roo from the group and added another pullet today, who apparently they recognize cause they are ignoring her. WWYD? Pull the lonely pullet out and get rid of her or with time will they eventually accept her?
