I am trying to figure out what is going on with my flock. We’ve never dealt with fowl pox before. I’ve been searching for answers every where I can think. Trying to determine if this could be fungal or parasites? Any insight is greatly appreciated, really worried about them. Some of them have some rough looking patches on the skin but mostly it’s isolated to black and white discoloration/spots on their comb and waddle. The legs look normal, really the faces that are concerning.
