What could this be?

[mviera101]

This wart? was just noticed on Hope who is about 3 months old. She is one of our schools mascot chickens. I was going to attempt to clean it with Hydrogen peroxide and some Neosporin . Any ideas of what it could be? It is concerning because it just showed up, It is hard to the touch, and the skin appears broken.

Thank you

Betadine would be better than hydrogen peroxide. Perhaps flush with saline first then the betadine and then the Neosporin.
I don't know what it is.
