After months of searching I payed $30 for 12 runner duck hatching eggs..... I sat on a waiting list for 4 weeks aftery initial purchase. The box came destroyed with 3 destroyed eggs, 2 cracked, and one with a hole in it. I was left with 6 eggs. I let them sit for 24 hours then put them in the incubator! I waited a week before candling them and none of them ever developed... I chalked it up to rough shipment.... Then I put each egg in its own ziplock and eggtopsies them..... They don't look fertile at all this is what all of the yolks looked like..... Are they fertile??? Maybe I'm wrong
