I am on day 18 for 11 of my chicken eggs and day for only one of my eggs. I was told when I set them to wait until midnight on the 18th day before preparing the eggs for hatching. Today I have been watching the eggs and making sqeaky noises to them. The day 17 egg is responding by rocking. A few of the other eggs(day 18) are as well. What should I do...it is 6:41pm now...should I wait till midnight before raising the humidity and putting the in the egg carton? or do it now?
