Glad they made it safely! Did you candle them to see how the air cells look? I would incubate them upright in a carton unless the air cells are really intact. I have a couple hens that are 2 to 2 1/2 yrs old and they lay quite large eggs, as big as a silkie egg. My pullets lay tiny eggs and I find them much harder to hatch, unless you are a hen, of course!
