I have a two year old salmon faverolle hen with a swollen foot. It's right where the webbing is between her two toes (not the extra one her breed has but the ones in the front) and it's very large, pink, warm to the touch, and is painful to touch as well. It's starting to happen to the other side of her two and on her other foot too. She has a black scab on both of her feet, but it's not swollen there. We just got over a bumble foot epidemic in our coop, so is there a chance that this could be it again? If not, what is it and how should I treat it? We are trying to avoid taking her to the vet because of some recent pricey vet bills with another chicken.
