Need help with identifying skin problem on the chicken chest

[April 12]

Thank you, I will do it

The chicken is free range.
It's blue cream, that I applied, in surrounding feathers

I was thinking if she was enclosed to a run maybe rubbing her chest along the wire. So that rules that out.

It may have been originally caused from another chicken pecking her. Feather lose like that is unlikely to grow back till her next molt. So keeping it covered for protection till she grows them back is a good idea if it's from pecking. Unless you do discover lice or mites.
I personally like coconut oil for areas of feather lose.
