If I want my Ruth (male name to be determined yet) to have enough ducks to keep him satisfied (without hurting my chickens), how many is the minimum? I already have one female muscovy, but one isn't enough, right? I am almost positive that Ruth is a he because of the sound of his voice. He/she has taken to chasing around my mutt chicken grabbing on to her neck. Sorry about the quality of some of the images.. Hope it's enough to tell me if Ruth is not a Ruth at all. He has a silver belly with a darkened head.
