I have really enjoyed all of the information I have gained from the site and its members. I had 24 eggs given to me to hatch in class this past year, only two hatched. I did not have an egg incubator so we made do with a bacteria incubator and we lost temperature control for a 1 1/2 days. All this being said it was so much fun and the students and I had a blast. I decided to do my own eggs this summer to show my son how neat it was, still using the bacteria incubator, but much more controlled environment. I bought the eggs at a flea market they are due to hatch June 9th. I have candled the eggs and there are two that seem to be way more advanced than the rest. Is this normal?
