Hello All I have a barred rock with injured leg. It has become very swollen. She does not walk. I don't think it is bumble foot, but something in the "knee" joint. Still eating and drinking like normal. Leg is not "floppy" loose like a break. Seems to be tendon or possibly infection. She started limping, with no swelling. Now, she doesn't walk and very swollen. Is there an anti-biotic or anything I can give her before......... .
