I don't know where you are located but look on your local craigslist or Ebay for sellers that are closer to you. The shipping process is incredibly hard on hatching eggs and can end up being very expensive. I have found better success buying only from sellers that are no more than 1 state away from me.Just hatched eggs off eBay - Serama bantams. They hatched yesterday, on day 19. The auction was for '16+', I got 18 well wrapped and packaged. One of them had a chip in it, a tiny spot, but I didn't see it until just a few days before hatching. I've never hatched any kind of eggs before. My results were;
Using a Zoo-Med reptile egg incubator, forced air, set at 100f. It doesn't have half-degree settings, but, hey. I already had it, and it had never been used. Hand turned every four hours up to day seventeen, marked with a dot on one side and a stripe on the other to be sure I didn't overlook anyone.
18 eggs to start.
-8 that candled clear on day 10 or so, and when opened showed no development. (Could be they were infertile, or too old, or x-rayed in shipping. Who knows.)
-1 that showed a 'bad' spot on day 10, opening showed an embryo that started but was blood-ringed.
9 eggs showed development and promise on day 10.
-3 on day 17. Emryo formation, but no development.
6 eggs showed development and potential, though I couldn't tell on movement, on day 17 when I 'locked down'. I had conflicting information on whether Serama would hatch on day 19 or day 21.
-4 on day 19, when they hatched healthy, strong little puffy golf balls!
That left two eggs that hadn't pipped. I didn't see movement in either of them.
-2 on day 20, when I carefully 'pecked' a small hole in the shell to check for blood vessels. None in the air pocket. Further opening the hole revealed dead chicks that had never internally pipped, both with full feather development and an egg tooth. One never absorbed any of its yolk sack, the other appears to have ruptured the yolk, since the egg started leaking yellow as soon as I opened the inner chick membrane to try and find out what went wrong. Both had vein structures, but they didn't bleed - the chicks were quite dead.
End results; 4 beautiful live chicks, 8 duds, 6 that might be my fault for loss, or might just have been natural fails.
Conclusion; I'll undoubtedly be doing this again. There's another Serama breeder that sell on eBay whose eggs I'd like to try, and I'd like more Serama! Maybe next month.
Incidentally, the one with the chip in it, which I covered with a tiny piece of scotch tape to hold humidity in when I saw it, was; The smallest egg. The first egg to hatch. The strongest chick out of the egg. The first chick to figure out food and water. And among the four, the smallest, the most active, and the leader.
