My Hen Penny has several small black spots on her comb and based on looking at pictures online, I am pretty sure it is fowl pox. I had another hen that had 2 very, very small spots a couple months ago. I put betadine on them and they went away. The ones one Penny now are larger and more. Does Betadine work to get rid of the spots? Is there any other remedies out there? Should I be worried that this could make he very sick? Thanks for any advice!
