Ok, we are new to having ducks and didn't get to pick what kind we wanted. We originally got 2 of them but one died within 24 hours of getting them. This one is now about 7 weeks old and is almost completely feathered out. It is already quacking which I read somewhere that meant it was female. She's very funny and stands up and runs everywhere she goes, getting from point A to point B as quickly as possible. We think she is a runner duck and that she is possibly a fawn and white but we aren't sure. Any help?
