They come and go, most of the nights they sleep on that floating island on the pond, where they have been raised by their mother, but sometimes they sleep somewhere else. - The neighbors also have ponds.I've never seen a Mallard go through molt into Nuptial plumage I thought for sure one of Hillbillys drakes might have fathered this one.
@WannaBeHillBilly are the Mallards now part of your flock go in every night with them for safety?
They hang out with my flock to enjoy safety in numbers - at some times there lay up to 59 ducks around the house, every step another quack… And they help themselves to the pellets. But i have not seen one of them in the duck-house and they don't walk inside with the other's at night.
I am still not sure if they will stay here over winter or if they will be gone one morning.Told them they're welcome to stay and will be fed, but instincts are strong.
From my childhood in Germany i remember, that all Mallards and Geese (and a lot of other birds) were leaving for the winter, but as the winters became milder and milder more and more ducks and geese decided to stay. Now they have turned into a nuisance in parks and lakes and it is strictly forbidden to feed them.
