What are these ducks?

He makes a whisper noise except he's social like the mallards (He got raised by one).

Muscovy x "mallard" type ducks, we call them Mule ducks in the US. I've raised them a few times. They make excellent eating ducks.

Yeah they do make great meat ducks. I've never raised any for that purpose though. I've only bred one.

At the moment I think he's still in eclipse moult so he won't be as green as a Cayuga on his back.
