I have a drake and a hen. My drake is just plain MEAN to my chickens sometimes. He does not like to be handled at all, the hen is even worse. And they are water hogs. I have to put out a special pan of water just for the ducks. Currently my drake has puss in one eye. I am very worried, but don't have a clue what to do for him.
I got mine from Thiesen's Farm Store. I also got 3 Pekins at the same time. The Pekins went to freezer camp, but I kept the Rouens because the hen was laying eggs, and I was hoping for ducklings. She quit laying eggs when winter hit. If she doesn't start again in the spring, it will be off to freezer camp or.... I might just turn them loose down to the pond with a dog carrier for shelter, and see if they can survive on their own. Lots of grass, berries and tadpoles to chase down there.
My hen laid a white egg that was about the same size as my chicken eggs. It was easy to tell them apart, because the duck eggs have a much thicker shell. I didn't notice any difference in the taste.
