I am on the fence about getting a few ducks and my options for getting what I want locally seem to be pretty slim. I was thinking of ordering from Metzer Farms as I just want a few and just females so i was thinking of ordering one each of Welsh Harlequin, Buff, Rouen, Black Swedish, Cayuga and White Layer so I could have a variety. Six is actually more than I want but that small order fee actually equals two ducks . Is it ok to have one of each like that? I tried to pick ducks that were considered calm and about the same size.
