Being rather new at hatching eggs, I've just had an experience that I haven't found any info about on BYC. Is it possible for FERTILE eggs, upon candling at day 6, to have no embryonic development and no veins/blood vessels? The yolk themselves are intact, as I opened them to check them out on day 7. They look like a perfectly normal egg on the inside, no blood rings, nothing abnormal...they look just like an egg that you crack open to cook. These eggs were shipped to me. I have had "scrambled eggs" that I've cracked open to find the egg yolk busted. But these eggs are completely normal...just no signs of development. These eggs were in an incubator with some Delaware eggs. I moved the Delaware eggs to a hatcher, where 3 of 4 hatched last Monday. So it's not the incubator settings. Please help me figure this out!
