I went to a park today, they had chickens, I saw their feet and I'm convinced that they have that problem, is it called "scaly leg mites"? They have the scales peeling off and it looks like one of the chickens has a growth on their feet, possibly a buildup of the peeling off scales ? I care about chickens a lot and i would be happy to treat them without the park owner even knowing but they might see me.
Also, the same chicken with the growth, I saw them putting their beak in their feathers behind the head, didn't look like it was preening themselves, is it lethargic ?
And the photo of the black hen, is that frostbite ?
I have put some pictures below, please could you tell me what the problem is and what treatment they need, also how do they get treated ? (amounts etc).
By the way, i'm saying "it" and "them" because I think at least one of them could be a boy or girl.
Sorry about this, i'm just worried
