hi i have a Peking duck he was friendly until i got a female now he bites and is mean he doesn't really bite or chase me unless i call him but when other people come over he jumps over my electric fence and chases and bites people and they get red marks but how do i stop him from chasing other people and biting them? also don't say any thing about my grammar.
You should ask over on the Duck forum https://www.backyardchickens.com/f/42/ducks Most people here only have experience with chickens. I suspect he is protecting the female. I have never had an aggressive drake so I don't know what to suggest, other than asking the duck experts.
