I've researched on the forum but I'll ask since my situation seems different. We were outside today and heard a commotion in the coop/run and saw 5 of our BSLs attacking our 6th one. I ran in the coop because she stuck her head into the hole of a cinder block and wouldn't move. When I picked her up one of her wattles was a bit bloody and her comb seemed droopy. I put her back down and immediately two girls chased her and one grabbed her comb clamped down and tried to rip it off. She went up on a roost and they left her alone. I moved her into the segregated pen and cleaned her bloody wattle. I left her in there because I was afraid it would keep bleeding and they would go after the blood. The girls were raised as chicks and we've had them for a year so no new flock members and they are all BSLs. She is one of the 4 that look identical. Her feathers seemed fine and it seems they only wanted to peck her comb and wattle. I am guessing she might have cut herself and they just went for blood but I'm really not sure and it was a tiny cut. The comb had no cuts but it seemed droopy compared to the others, I wasn't sure if it was just from the attack. It is a bit pale too so I started thinking maybe it was worms but I might be paranoid because nothing else is wrong. She ate and drank and laid an egg after being separated. My husband is now worried that because she is separate when we put her back they will want to attack even more. If it seemed to be one attacking I was going to separate that one for a few days to see if it helped. Any advice or ideas of what caused this? We had a really bad storm that caused flooding in our area. The coop isn't flooded but it's wet. They have sand in the coop.
