I just got home with 5 new pharoah quail hens I put them in with the other hens everyone seems fine but I noticed a "tumor" looking thing on one of my hens feet, I now do not know if its a new one or old. Should I Cull it out or will she be ok? It almost looks like a REALLY bad blood blister but there are 2 on one leg she is acting fine not any signs of illness. What to do???
