If ducks don't work for you, then they don't work. There is no way around that. Someone in your area will like to have a nice flock of laying ducks.
I've cut my flock way back, because my son's brother has moved in with him and he can't eat duck eggs. That means when I cook, I must either cook two dishes, one with duck eggs and one with chicken eggs, or else I can make everything with chicken eggs and only cook it once. I can't justify feeding a flock of ducks, buying feed, and then going to the market and paying for chicken eggs.
