I have several birds with whitish/green earlobes and some with white or dark spots on combs too. My rooster also has some dark spots on his comb and is missing a lot of feathers around his neck but I saw one of the hens “grooming” him quite aggressively so ?? The skin underneath the lost feathers looks rough and a bit scaly.
They had a hard snowy winter and were inside a lot in a too-damp shed; we have since moved them out into a brand new coop and they are outside most of the time now. I’m guessing this is favus but hoping for confirmation. Am treating with a farm animal antifungal/antiseptic spray for a few weeks to see if it helps. Birds happy otherwise. Laying. (Do I need to discard eggs during fungal treatment?)
Worst affected hen (she had some frostbite this winter too and tips of comb haven’t quite recovered)
