Well, I am wondering the same thing here and as my eggs come and I incubate I will let you know what I find. 5 goose eggs, pine shaving enclosed and bubble wrapped- so far 3 look good, 2 possibilities 7 peacock eggs- wrapped in newspaper - 3 look good, 1 quitter and 3 maybe's 7 giant blue cochin- came in egg carton I think- none look good, but only 4 days out 10 black copper marans-came in egg carton and individually wrapped--can see some air cells, hoping 20-30% make it, but hey it is better than none and still a bit early Still waiting to candle the white plymouth--egg carton, delaware-individual in newspaper Turkens and blue frizzle cochins coming soon. Will update I have heard that if the PO x-rays them they will not hatch well or at all. Is that true? Even if they are marked do not x-ray I am sure that Uncle Sam isn't gonna let them through security without x-raying them. What is your idea on that?
