I have a hen who had a small bumble on her foot. I treated it and wrapped with PRID until it was healed. She has no more scab or even noticeable spot where it was. She is however limping. When comparing her foot pads the one with the bumble is markedly swollen. It does seem to be firmer than the other footpad. It is NOT warm/hot however. She is completely normal in every other aspect. Is this normal when a bumble is finishing healing??
