ty.......... I had a huge problem seeing the aircell I dont know if it was just my light or what.. I did try to candle an egg with a brighter light an egg I had in the fridge would that make a differnce being from fridge as aposed to a hatching egg?
ah HA that would be it everyone was laided literially 3 days before put into incubatorsometimes it's hard to see the air cell. If the egg had a dark color, it may be impossible to see without a super bright light. I had a chick from an Olive colored egg that I was never able to candle. Also, if the egg is very fresh, the air cell could be very small. A store bought egg is probably much older than a hatching egg and the air cell might be bigger.
