We have 3 mallards (1 male, 2 females) running around the neighborhood. They are semi owned by my one neighbor who feeds them but live completely outside roaming between 4 ponds/ properties. I actually find them sleeping in my pond quite often. This morning I found an egg sitting right at the waterline of my pond. Are these eggs she drops all over the area not viable for hatching? Are mallards just not very broody? At least this egg has a hard shell. The ones from the last couple years were jelly eggs with a soft shell. Can I cook it up and give to my dog? Ultimate goal would be to place under one of my chickens when they get old enough to be broody. If the mallard doesn't want to hatch a viable egg, maybe one of my chickens will.
