Combs and wattles bleed a lot. They are very vascular. It is common to see little black scabs on combs resulting from minor pecks, usually received at roosting time and when eating. I don't bother to treat unless someone got a little bite taken out that really starts bleeding.My leghorn has some blood around it’s comb! It also has some black spots on it, I was assuming this is dried blood. What can I do to keep it healthy??? I did spray it with a something recommended, forgot the name.
