Two wild female mallards joined my flock a while back. I named them Bonnie and Clyde. A few days ago, they disappeared, and I thought they had migrated. Well, a little while ago, when I was out with my ducks, Bonnie flew in, no Clyde in sight. Huh. (Bonnie was always a whole lot friendlier than Clyde, and now goes in the duck-house, where there is food.) Guess I'll put her to bed with mine tonight if her buddy doesn't show up. Wonder what happened.
