I've hatched both ways, and I really like hatching in the egg cartons. (paper cartons) I had a much better hatch this way and the eggs were not being kicked around by the chicks that had already hatched. Out of 11 viable eggs (had 13 in there but 2 had died before lockdown) I hatched 10. I'm not sure why the one that did not hatch died. It had pipped, then died. The chick looked fine when I opened the egg, so who knows.
