Hi, I have a chicken whose been with us for probably about a year and a half. Sometime last month I noticed a scab on her foot. Ever since I have been spraying it with vetericyn + poultry care but it has not been getting better. I was outside watching the chickens while I let them roam around my yard when I noticed she was trying to lay an egg and one of my other chickens kept on pecking at her scab cause if her to bleed. I have them both separated right now but I’m worried about her and would like to know the best way to approach this so her foot can heal, thank you
