mallards with Swedish blues

[cnaudiffred]

My local feed store has some mallard ducklings an I want to buy 2 of them tomorrow..I am gonna try to get 2 female as I already have 1 male and 1 female Swedish blue. I would raise then for a couple months apart I guess and then introduce them together? I'm also assuming different breeds together is fine? Just want to know. Also if I can distinguish the females out and buy those the male Swedish blue will breed those also, like the female blue? Thanks in advance.

Keeping different breeds together is fine as long as they are around the same size. Swedish ducks are bigger than mallards though and this can be a problem if the male swedish tries to mate with the female mallards. Because the mallards are so much smaller, he may hurt them.

Each drake is different some may be satisfied with one female, some may mate with more. Some are more aggressive with mating than others. Getting two female mallards may work, or it may not. It depends on the drake. Good luck with whatever you decide .
