Good morning. My poor little man rooster has developed this infection or something over night. We noticed it yesterday but only the size of a small pea and no blood. We thought maybe when a bobcat got into the coop he was trying to protect the hens? He’s very protective of our hens. But then today it was 20x the size. We checked the other hens snd they are ok (thinking mites) they are all eating good, laying eggs and energy is good. I have no idea what this could be or what to do. I did read that if it is mites to give the chickens garlic as mites don’t like garlic in the blood?! Any help would be great. We are new at having chickens. It’s been 9 months now and not one issue.
