This is the second year that I have ordered fertilized eggs to hatch in my classroom from this seller. I ordered 6 eggs and was sent 8. I just candled the egg for the second time and 6/8 of them have a live chick in them. 2/8 were fertilized and stopped growing somewhere in the process. Considering that these eggs are sent through the mail, I think that is amazing odds. I will continue to buy from this seller and
