Hi, I have a drake that mates with one of the females but is very rough. He has stripped all of her feathers from her neck and has now ripped the skin off. I have separated him from her but any opportunity he will mate with her and rips the skin off. I am worried that she will get an infection. I have clipped his wing, so he cant fly into her separate area of the run. I have 2 other feamales but he,s not as rpugh with them. Any ideas what i can do?
