I have a Silkie in a mixed flock. It has been very caring and motherly to all the chicks it was raised with. One of our two straight run chicks was a rooster, so he and his favorite hen went to live on a real farm. I live in suburbs, I can’t have roosters. Suddenly my motherly wonderful Silkie is crowing and attacking the hens, jumping on their backs and ripping at feathers. She hasn’t gotten feathers out, the girls all look ok, but they’re so stressed! I gave her a time out yesterday away from the flock and she was so docile and quiet with me. This morning I was out with the chickens when they woke up and she’s right back on the attack. Any tips? There’s 10 chickens total. I think there’s some space issues in the coop but I’m free ranging them all day and that helps a ton.
