I have one male and one female duck that I raised from a few days old. I have had them for over a year now. When they mate he bites on the back of her head to the point of her bleeding. I put antibiotic on the scabs every night and have started using pick no more ointment to try to get him to grab on to her less. He will grab on the side of her head near her eye and I am getting very worried that she will lose her eye if he keeps it up. I am at a loss for what to do. Should I get another female to up my female to male ratio? Should I permanatly separate them (I know they need each other's company so I am not sure that would be a solution.) I have thought about trying to re-home him and then get her a female as a companion. They free range when we are home and I have tried to give them things in their house and run- mirror, treat balls- things to try to occupy him. Any thoughts or ideas would be appreciated. Thank you!
