Mackay,
There must be some sort of regional or demographic variation going on. Check out iamcuriositycat's post about not being able to provide enough eating or hatching eggs in her area.
A local farmer (dairy) told me last year I ought not get ducks but chickens, because no one wants duck eggs.
A local retailer told me last week that he would sell my duck eggs at his store, and a neighbor has asked if she can have some because she loves duck eggs.
A friend has told me that if I end up with a drake and therefore fertile eggs, that she wants some to hatch. My runners are only seven weeks old!
Years ago I moved to eastern Ohio. Farm country. I asked where the local farmers' markets were. I got blank stares. There were no farmers' markets. There were farms all over the place, but they sold to wholesale distributors (beef, dairy, pork, mostly), no one to speak of grew produce, no apples, no pears, no cabbage . . . It was sad.
