I have quite a few wild mallards around here too, and my drakes sometimes fly with them. But my ducks always lead the flock and they haven't ever left. When I'm around the wild ducks won't land in the yard, but I've seen them out there with wild ones ocassionally. About a month ago my drake Nyasa would fly with a wild drake that lived nearby, they got to be friends! Every day when Nyasa took off the drake would join him and they'd fly around for a while, but now the pond dried up where the drake lived so he moved on. It's actually really awesome to see your ducks up with a wild flock, although when the wild ducks outnumber my ducks I have been a little nervous!They do! Question if my mallards saw wild mallards flying would they try to join them? Because where I live in WI there are quite a few. I will post some more pictures later.
Anyway, I'm sure they won't leave, although I would be a little more careful this fall not to let them fly with other mallards, the instinct to migrate could kick in. But this summer I don't think you'll have a problem!
