My Sumatra rooster decided to pick a fight (through the wire) with my Crevecoeur roo. He sliced the back of his leg open (right where his "thumb" and leg join together. I cleaned it out & put him on antibiotics. That was a week ago. The leg is now swollen (larger than the other one) and he's not really limping but stands one-legged a lot now. I've recaptured him and cleaned it up again and the wound is almost non-existent already but the leg is still puffy. I still have him on antibiotics. Is there anything I can do for the swelling? Oh and he's got fresh pine shavings (about 6" in the coop) and new sand in the run.
