Sorry for tardy answer. I thought I'd get an email if anyone responded. Never happened.
The deformed foot healed after about a year and I can't even see it. No more limping either. Total mystery to me.

I have a Rhode Island Red hen who has two painful bulblous growths. One on each side of her foot. She is only a year old and has had this condition for 6 months. She is a regular layer too. It is painful and she barely allows it to touch the ground and has to roost on one leg at night...
