This spring I added 6 new hens and 2 ducks to our flock of 11 hens. One of the ducks is a male. He has recently began showing romantic intentions to one of our hens. She is an older hen. He is a white pekin duck. She is a silver lace wyandot. He is relentless. He chases her all over the yard. She has been coming up on the deck during the day to get away from him. Is there anything I can do? Or is this just normal?? I feel bad for her. She literally hides behind me when I am outside so I can protect her.
