No yolk is quite odd.
Sat on eggs is bad.
My first shipped turkey eggs all didn't go at all.
My second set of shipped turkey eggs all are, except a couple, about to hatch.
My first chicken eggs that were shipped developed but my bator freaked out and killed them.
My second set of shipped eggs went about 70%. Either they went or they didn't. No middle quitters.
My third set of shipped eggs all but three developed despite horrid handling resulting in bad air cells.
My fourth set, all but two hatched, one clear - one post hatch quitter.
LOL Etc. since the addiction doesn't appear to be stopping and there have been and will be more.
In the majority if you luck out on a seller, shipped eggs can go well. Many of the
ebay/eggbid/ovabid sellers are BYCers. And those are the ones I now stick to most often.
Better luck next time. I would at least give the seller the opportunity to make it right.
