I am so bummed -- I put 4 eggs in lockdown 3 days ago (the only ones that made it out of 24 shipped Ameraucana eggs) and so far nothing is going on and today is D-day. Last attempt, I got one little chick out of 12 shipped eggs (but we have become very close ) The first batch had terrible air cells, but these last ones had great air cells. All but a couple started to develop, and then they just started quitting. Five blood rings, and several that looked like day 12 maybe. They had all their feathers and little toe nails. So sad. I live near Colorado Springs, and the elevation at our house is over 7000 ft above sea level. Has anyone had any luck at all hatching shipped eggs at high elevations? My own hatch out fine. Plan B is look for some baby chicks and go from there.
