I have a 3 month old female welsh harlequin that is biting and and attacking not only me but others too. She is with a male blue swedish and a male cayuga. I have noticed that she has kind of become alpha of the group. When you get close to her or are trying to round them all up to go into their pen, you can noticably see her head shake (vibrate) then she turns and comes running towards you beak open. I stand up to her, but the little kids when they are trying to play with them gets super scared of her and runs away. The males havent done it, but I want to try to get her to stop, before the males start, and someone gets hurt. Does anyone have any suggestions of what to do with her to try to get her to stop? I'd really appreciate it any suggestions of how to help.
