We have very good layer duck hens and they set on their nests but the snakes keep eating their eggs. I bought incubators and now I'm collecting their eggs every day and artificially incubating them. My question is, when the ducklings are old enough to go out on the water with the adult ducks, will the hens accept them? Our ducks are free range, we have a large pond with a center island for their protection from predators..except snakes.
