Ya haha that same thing happened to me this year, thought it was Normal to Lesser turned out that the one time I had the normal with the Bumblebee did it, ended up with 2.1 Normals and 0.2 Pastels, quite the surprise when you cut and see a pastel looking up at you! Good luck and if it were me I would wait until day 50-52 before I cut.
Lol. But congrats on your eggs. And I mean I rather not slit the eggs cuz I don't want to mess up. But thats why I asked if it's necessary to slit the eggs. I rather just have them come out on there own.
