I've had mixed results with foam shipped hatching eggs. due to araucanas rounder nature, I found a lot of them ended up flipping in the cell. so although the eggs looked fine there were a lot of ruptured air cells. I think I've had eggs shipped pretty much every way to me, but the most successful has been eggs wrapped and then oriented correctly in a carton that has been well padded and secured in a good sized box. This is just my experience though.
