Thank you duggat, ducks are just great birds. I live my chickens but ducks are really special, especially call ducks and I could just watch them for hours. Very therapeautic.
My guess then for Karen is that she is a mallard call duck cross although there looks more call duck than mallard her whole shape is more rounded like Angie than long like Molly. The flight feathers can be brilliant blue or brilliant green. They look such a lovely pair, will you let them have babies? they would be very interesting to see.
