Does anyone know what this is? Any thoughts or advice would be so appreciated! One of my chickens has a small hard lump on her footpad. It doesn't look anything like bumblefoot (doesn't have the typical scab) but feels more like a piece of cartilage...or maybe a wart..? It dosn't look infected but she is limping heavily. I understand that bumblefoot is caused by staph infection that gets into the tissue through a cut. Or can it be more like an internal abcess? Someone suggested penicillin - it didn't work. I've done a lot of research but still don't really know what it is. Thank you everyone!!
