I have a 5 month old pekin drake and he has started to be really mean to my other ducks. none of them can swim with him in the pool all but for my almost one year old pekin ducky momo. i don't know if he is just trying to say that he is the boss but i would like to know if i should move him out of the coop. i would like all the help i can get. i just dont know what to do with him.
