My geese, cover their eggs till they have enough for a clutch. THEY ARE ALL DIRTY. Gross dirty eggs they step on them, they roll them around, they stand on them, some they crush and they still hatch out good goslings.
Those eggs in that box look great, in fact they look better than the ones I have outside on that nest. But they will still sit on them and hatch out some. You guys don't know geese or you wouldn't say that.
They are gross and nasty critters their feet drag all manner of gross material all over those eggs but they do stay 90% dry. They cover them and keep them covered, and if it's going to rain, they set on them. That tells me DON'T GET THEM WET !
I bet all those eggs hatch and those embdens are great birds I love mine.
