Yes..Try it? Might work?..Mallards come here to get my Call hens each spring and my Drake tries to leave too..You could try putting the females in a dog kennel and bring them near the drake, Them qaucking and talking might ecourage him to come back or you could set a live trap and bait it with some food and see if he is hungry enough to enter the cage. Hopefully he comes back ! I know how crazy mallards can be sometimes.
