One of my hens suffered a nasty wound under her wing from my roo being too frisky...it's pretty bad...an area about the size of a tennis ball is torn away down to her flesh. I cleaned it out with medicated wash and packed bag balm, the medicated ointment you use on livestock, into the wound and took an old baby onesie and fashioned it into a makeshift bird shirt/bandage deal. I basically stuck her wings through the arm holes and tied the loose ends in knots to keep it on. I put her in a dog crate to keep her seperated so she can heal and she's eating and drinking fine with her shirt on. Should I keep the wound covered? I'm worried about flies and maggots getting at the wound if I leave it uncovered. Also, I have both Pennicillin and Baytril, should I give her and injection? She's about 4lbs, so It's 1cc dosage, right? Where to I give her a shot at if I do give her one? I'm assuming in the breast? Any advice is appreciated. Thanks all!
