I feel you pain! I have had this happen twice with eggs from different sources. The first time shipped eggs some from two different breeders, in different states. All that made it to lockdown from one breeder hatched and none from the other. I blamed the postal system. The next hatch I picked the eggs up from the breeders, I bought eggs in state, the same thing happened. All from one, one from the other. Then I read here on BYC that someone else whose eggs hatched the same week and were shipped from the same breeder, had the same results I did, only one hatched. I think the breeder has a problem, not that I could prove it. I am not an experienced hatcher, and I have been learning on shipped eggs, but I do my homework! I would have totally blamed myself if the results hadn't been so clearly divided along the breeder lines. Statistically speaking, it is very unlikely that it is anything you did, since the other 2 breeds hatched out fine, if it was your fault it would have been reflected in the hatch rates of all the breeds. I would hesitate to buy eggs from that source again if it was me. Sorry you had such a disappointing hatch.
