Does anyone know what the best type of antibiotic is for a chicken with a very deep wound in her back. My dog got a hold of one of my very young hens, she really should be dead (by the look of her injuries), but she’s staying alive so I’m going to try to treat her. Her little delicate skin just broke open and you can see all the way into her organs. But she is still eating drinking and sitting upright, and looks bright. I just need to get her started on something ASAP so she doesn’t become septic. Any suggestions???
