Last night I heard a hen scream and when I ran out a racoon had her. Her two babies were okay but it appears she has some deep gouges on her back and left leg. I have her in a pen with her babies but she is having trouble walking, no broken leg, I can see, maybe got twisted & pulled. What antibiotic or sauve can I put on her to protect from flys? Is there any type I cannot put on her? I have several for my horses I was thinking of trying.
