We have a small flock of four birds, 2 Rhode Island Reds and 2 Easter Eggers. About 2 weeks ago or so, we started noticing small, black spots on the comb and waddle of the Reds. Online research is inconclusive. Whatever it is, it seems like a mild case, but we want to clear it up, whatever it is. Also, one lobe of the comb on one of the Reds became swollen and bruised looking. We put some "no-peck" ointment on it to try to keep the others from messing with it, but now that lobe seems to have fallen off. The girls are about 24-25 weeks old now but still have not laid a single egg. Please look at photos below: Here's the before and after of the swollen then missing comb lobe: Any suggestions?? Thanks!
