We still haven't had any hatching yet, so we are worried that we did something wrong. We have read that if the temperature is to low or to high the eggs can hatch late. It is the 22nd day for 1-5, 21st day for 6-10 and the 20th day for 11-13. Next Sunday we have 18 eggs that could start hatching, those eggs have a bigger chance of hatching because when we candled all the embryos we could see were developing. We are all very anxious to see some eggs hatch, so we have been checking on the eggs at least three times every half hour.
