I have two hens with severe wounds under their wings. (It's amazing what happens when you leave for 2 days ) I have cleaned the wounds, and applied antibiotic ointment. There was a lot of dirt in the wounds, so I think I should give them an antibiotic. The only one I have on hand is Bio-mycin 200. What would be the dosage and how should I give it? I would assume injecting it into the breast or thigh muscle if it can't be given orally. The feed stores are closed for the weekend, so I can't get anything else. Any advice will be appreciated. They are 2 of my Delaware breeding hens. Thanks.
