My half-grown turkey has swollen and puffy feet and toes. His legs look perfectly fine, just his toes in particular are puffy. I can't see any sign of trauma or discoloration but they feel warm to the touch and he can't wrap them around his perch. He looks like he is in pain. I strongly suspect it is some kind of infection. Any ideas? The only antibiotic the feed store has is tetra-something in a small package that treats 400 turkeys!
