I put leg bands on the ducks today and got to hear their voices indivudually. I have 3 male pekins 3 female pekins and 2 female mallards. I think thats a pretty good ratio isnt it? Will that be workable or am I going to need to get rid of one of the males? What do you guys think? The pekins can mate with the mallards too right? So thats 5 girls for 3 boys?
