I let my ducks,goose and chickens out between 6:00 & 6:30 every morning. I give them fresh water and feed and while I was doing this I heard a noise like a squeek and looked around and my pekin drake was mating with one of my little runners. I didn't see her at first because she is so little and he is so big and they were in some tall grass. When I realized what was happening I ran over and knocked him off of her. She is only 3 1/2 months old and I sure hope she wasn't injuried internally. I was so angry at him that I locked him in a pen by himself. I put his mate in with him tonight. Do ducks usually mate this young or did he rape her. I'm still angry about this.
