I have discovered that 3 of my hens have TINY black and white bumps on their combs and wattles and one has a strange red squareish mark on her beak and her comb seems to be turning slightly purple at the tips and another seems to be making this weird quail-like sound (not a normal cluck) after I caught the tiny mouse that has been sneaking into the run and stealing their food. They all have parts of their combs that are bleeding. I have already gently cleaned the bleeding parts and they seem to be slowly getting better, but the bumps are multiplying! Could it be fighting? A disease? What is happening to them?
Sorry if the pictures are a bit blurry. It's hard to take pictures when chickens are pecking the camera from all angles.
