I have 1 cockerel who has some brown dry wart like growths on his comband wattles and one on his eyelid.They are not scabbed over or wet just like a light brown or tan round raised areas on these areas.I think is must be fowl pox I don't have a camera no one else has it at this time.From reading on it looks like it is not really preventable other than shot we do have mosquits this year.
