I have three chickens and I went out today and one is being severely pecked to the point it’s bleeding. I don’t know what to do and I have no way of separating them as I only have one coop. It is a large coop it originally houses 9 and I only have three in there. They also have a large enclosure to walk around in so they are not in a tight confined space. I have sprayed it with an anti peck and an antiseptic spray however it doesn’t seem to be working. Please help as it seems to be in great pain. I have attached some pictures below
