Before I went on vacation I posted a topic about my roo that had red sores and cracks in his hocks. We were treating with peroxide and it seemed to be getting better. Now that I am home from vacation I can see what looks like bumblefoot on the back of his foot and he is limping again. I am thinking the infection that I saw initially in his hocks was caused by an undiagnosed case of bumblefoot. His hocks look worse than before. I have never had this happen, but we recently moved and the soil is very rocky and we have a lot of burrs and stickers. How do I know if it is in the bone? Should I even put him through the surgery/shots/wrapping or should I cull him? I don't like him very much, he is kind of a turd rooster, but he does keep a good watch on our hens. When is it too late?? Thanks for your input! ps We only have a CAL Ranch store here, I am pretty sure I can only get PenG, would this work on Staph?
