There is a whole folk lore about using the 0 crystal hurry hatch. It does no harm, you never loose a crystal so it is perfectly safe. I always do it, to kind of welcome my new baby dino. Some are sure it increases their odds. I think it does not, but I still do it. Your question probably needs more study. I can't say for sure on this one.
