I am noticing that my hens have scabs on their combs. I thought maybe the hens were picking on each other - - - - but I was wrong. My roo has suddendly became very active. I caught him today on my biggest hen ( one that kicked his butt about a month ago). He was using her comb as a handle - - biting it. He must be getting hold of all my hens because they are all showing damage to their combs. IS this normal or is my roo just being too rough. All my girls have their feathers - - - he doesn't seem to be hurting their feathers - - just their combs. Is there any thing I should do - - use the antiseptic for infection, use no bite to keep him from biting, OR is this ok behavior?
