I have been treating my chickens with Corid and wormer after getting advice from a vet online. My Silkie is still feeling under the weather for the past week, and the last 2 days has been bullied and had the back of her head bleed after being pecked by 2 Rhode Island Reds that she has been raised with. Why would they all of a sudden pick on her? Any ideas what to do about it? I have put up a temporary baarricade in the coop to separate her for a few days till her head heals. Will they always pick on her from here on out, or will it stop after she heals and is feeling better? I really dont have the resources to put up another coop and run for her .
