Odd growth comb/beak

[Lonelychick]

Juvenile polish/silkie has had this growth for a few months. It just keeps getting bigger and worse looking. I thought cutaneous horn... But wanted to see what others thought. I know his comb looks a bit yeasty... For some reason the polkies are susceptible to it (the other roos housed with them don't get it) I noticed my older gal (a duccle) has a growth now in the same spot... I'm wondering if it could be viral... AND found three mini horns on comb and a round one on wattle

Could it be from repeated injuries, maybe from hitting something on a feeder or pecking at things through hardware cloth?

@Wyorp Rock @azygous any ideas?

Here's the run-down on cutaneous horns. https://bitchinchickens.com/2021/11/15/avian-pathology-cases-3/

I don't believe that's what this is. I believe it's papillomatosis, caused by the papilloma virus. https://www.meandervets.com.au/blog/papillomatosis-warts-in-birds
