Just wondering if anyone has hatched duck eggs and how hard it is to do?? We want to get our boy some girls but didn't want to do so until spring however, it seems like the hatcheries are already selling out of some breeds for their spring hatch dates. We thought maybe it would be a great school exercise for our kids to hatch some and get the ducks we want at the same time. Any advice? What kind of incubator would we need? Is it different than chicken eggs? How long do they take to hatch?
