Muscovy ducks are not aggressive. In fact, ours waddle right up to us wagging their tails like a dog. Old Roy dog food is a favorite food of theirs. The ducks will eat it out of our hands.
The duck now lives with Poppy and me. It took some time for her to figure out that she is more like our ducks than our chickens. We kept her in a pen for a few weeks then Poppy took her out on the pier and sat her on the pond. That is when she really learned to be a duck!
She still wanders up occasionally and watches the chickens like she is looking for her companion, which makes me sad. That bird house she is standing on overlooks the chicken lot.
I suppose all is well that ends well. Still feel sorry for the little chicken though!
