Hi All, I'm a new duck owner (though I've had chickens for a whlle) and I've been away for a couple of weeks to come back and find one of ducks is looking terribly scraggly. I'm not sure if she's moulting or if she's sick or has mites. The other ducks and chickens are all fine and we are coming into summer in Australia so I guess I was just hoping from some reassurance from some duck experts out there... I'd really appreciate any comments. Thanks so much in advance everyone.
