My Blue Andalusian, Merryweather is picking on some of my chickens. She has ripped out all of Hector's (Sultan Rooster) beard feathers and ate them, and he just stood there and let her do it! I saw her try and pull my silkie over and My RIR Josephine has no feathers under her neck, I have not seen Merryweather pick Josephine's feathers out but I suspect it was her. What is going on? I have never seen her do this before today and she is normally a very sweet, quiet girl. I have her separated now but I do not know what I should do. I do not want to get rid of her but if she does not stop I may have to. Please help.
