Well, I read this post and put my mille fleur eggs in the paper cartons to hatch this time. 4 out of 5 did hatch. Now the only problem that I saw was that after the chick had zipped it was easy to get the top of the shell off their head but it took them forever to get their butts and legs out of the shell because they were upright. I am not sure this was a good thing, never had that problem with eggs laid on their sides.
