I woke up this morning to what sounded like my hens being attacked. I went out to the coop to see what was happening and let them out and found that all the hens (including the pullets who have been sleeping in nest boxes their whole lives) were cowering up on the roosts while one big hen chased our little silkie all over the coop and pecked her mercilessly. This is a hen who I have known to be a little mean, but it seems that since three of our hens went broody and we got rid of our rooster that she's gotten extremely aggressive, especially toward the mother hens and chicks. At this point, she won't let a chick walk by her without pecking it. Our silkie has lost all the feathers on her neck. Does anyone have experience with this situation? I'm planning to give her away to relieve the stress on the flock and I just separated her from the other girls, but is this a pecking order that will just re-establish itself once she's gone? Any advice is appreciated!!
