I need to find out some info. Over the years, I have been able to save my large white ducks after an owl or hawk would try to get them, leaving a back of nasty raw flesh. I have always sprayed peroxide and water mix to the injury over several days/weeks many times a day and they pulled through and grew new feathers. Will that work for chickens. The last incident is a barred rock with an exposed back looking like a rotisorie chicken at Krogers. She has remained alive and walking around for 2 and a half days now. I dont know if she has drank or ate. I have had her separated from the others and she pecks at her own back. She looked a lot better 2 nights ago. I put a cone around her neck and she acts lame. So I removed that thinking she wouldnt eat or drink. I am ready to go out and redo the back. I was told the blue spray works well for an antibiotic. Any help here?
