Still no idea what’s going on with my hens comb and growing black spots

[Ohsrsly]

Can you post pictures? It sounds like she may be getting pecked. I would continue to put Betadine on her scabs on her comb and wattles.

I’ll snap a picture under her vent today, I already put iodine on those scabs and her comb and wattles this morning so pictures may be a bit misleading at the moment!
