I attempted to hatch two some eggs from my Buff Silkie and Porcelain D'uccle, both developed well but did not hatched. When I opened the eggs after a few days, I found a dead chick, with the yolk & blood almost fully absorbed, but both were not internally pipped. Does anybody have any ideas about this? Once I collect enough eggs,(5 maybe) I will incubate them and see if it was just a coincidence.
