A friend gave me a few ducks last year.they mostly hang out by the tank but in the last few weeks they have started coming up to the shop to lay eggs. I have been thinking about trying to eat some but Im not sure. Is there anything i should be careful of or check out. They are mallard and one Peking duck. The drake got killed by coyotes last year so I know they cant be fertile. Anyone eat duck eggs. How long will they keep at room temp? Should I gather them every day?
