Hello I have 8 ducks, 1 male and 7 females Recently my drake has been chasing away a particular duck from the rest of the flock. He doesn't chase her like he wants to mate. He puts his head down, opens his mouth and chases her just far enough that she is away from the rest of the flock. I have removed him multiple times from the flock and without him in the picture the duck he doesn't like joins the rest of the females and they all get along great but once I put him back in with the girls that duck is targeted by him again. He chases her away from food and water and I feel so bad for her. The longest he has been separated has been a month and he has always remained in the area with the girls just separated so he can't mingle with them. Has anyone ever had this problem before and have a way to fix it? Should I separate him somewhere he can't see his girls? Does anyone have any ideas why he wouldn't like one particular duck? Any help would be great. Thanks! P.s. he's a Welsh Harlequin and the female is a production type Rouen.
