I incubated ducks. I have so far 2 that have hatched. Still in the bator now. I have a broody goose. She has been sitting on duck eggs. She gets off a lot and roams. Even stopped covering them to keep them warm. But is on it the majority of the day. I checked 3 out of guessing 20 or so are developing. Can I pull the developing ones and set the ducklings I currently have in the nest?? Can I fool mother goose like this? I'm afraid hers won't hatch (although I don't really know. This is the first year I have had the goose). And there are 30 eggs or so rolling around in the coop where she and the ducks stay.
