I just came out of a bad case of pneumonia and found out that a hen has serious bumble foot. I feel awful. I got the core out but her leg is hot. Penicillin? if so, how much in an injection and what size needles. We have had many cases, successful in all with minor surgery, but circumstances kept me from catching this case early. Any help on a Sunday would be greatly appreciated. Or, a portion of a penicillin tablet I have left over?
