As most of you know i had 3 ducks, Bel a male and 2 females Valley and Daisy. Bel was bullying the new duck so he has been rehomed. Daisy wasn't introduced slowly and we just presumed they would accept her. Now after a week of Bel at his new home Valley has began tearing out Daisy's feathers. She has bald patches. some websites have said that Valley has a mental disorder? and that it can result in death. What can i do to stop this cannibalism. What can i do to stop this? Please help!
