ok so this is going to sound a little strange but my male pekin duck thinks he is a chicken... so i have ruled out that he is fighting over females because he DOES NOT like ducks. So my 1 year old male mallard and my 4 year old male pekin have been getting into it the past couple of days and it is really getting on my nerves. the pekin is the one that usually starts the fights. we adopted him from my fiance's work and he had never seen another duck in his life. that is why he thinks he is a chicken because he only grew up with chickens. he does not like the other ducks i have and just hangs with our chickens all day. maybe he is fighting because he just hates other ducks in general? he will pick fights with my other ducks too. not sure what to do. he attacks my mallard in the water and i am afraid he will drown him if i am not home to stop it. any suggestions on how i can get this to stop?
