Hey chicken gurus, I am not finding consistent depictions or photos of favus. Attached is a few pics of my Favorite hen who has some questionable lesions of her comb. She is 1.5 year old olive egger who was rescued from gross conditions a year ago. No other hens have these lesions, despite close contact. Gradually, very slowly getting more black pigmentation. Doesn't appear to be bothered by it. No other skin problems. What does this look like? P.S. she is also babysitting 3 three week old chicks. Any thoughts any recommendations would be appreaciated. Thanks! Another. Love this hen.
