Query: praying mantis eggs

I bought these for my daughter's praying mantis kit and they arrived super fast. Its been almost 2 months now and they haven't hatched yet. I don't think it is going to happen. Sadness is upon me. A friend bought 10 egg cases from another place on amazon and their eggs came in mid-hatch....little baby praying mantis everywhere. Seems like a hit or miss item...good luck.
