I would suggest for a school project, try to find a local source where they don't have to go though shipping. Shipping does such a number on eggs that often hatches can be extreemly poor. It's so disapointing to see kids sad that nothign hatched. One year I brought some chicks to a class wh o had been trying to hatch eggs for 2 months. They were on their 3rd batch and it wasn't looking good.
