nothing. I had 15 Ameraucana and 6 brown eggs(I think Barred Rocks) set in my Sportsman. I usually only candle once, when I'm moving eggs to the hatcher... and yesterday was day 18. Not one, not a single one, of the Ameraucana eggs showed any development at all. Nothing. No indication that they ever even started. The brown eggs show good development and got moved to the hatcher as scheduled. I'm so bummed as I had to wait a bit for the Ameraucana eggs since the seller's hens weren't cooperating. The brown eggs were tossed in on top of my purchase as extras. So, all the eggs came from the same source, shipped the same, set the same, etc. ::: sigh ::: Sorry for the "poor me" post... just had really looked forward to some true Ameraucana's.
