So this past May we brought home 4 ducklings from my daughters school which they hatched from eggs....a indian runner, a blue swede and 2 mallards. About a week ago we started having problems with Quackers who is the only male and the Indian Runner. My daughter was pulling weeds and shushed him away and he came back and popped her on her head multiple times. Now any time I walk away from where ever he is near he starts chasing after me and biting my pants. He does this to our chickens as well. I need a solution to get him under control or hes going to need to go else where. Any help is appreciated!
