Hello New to the forum. I have a r-com 3 egg incubator with a candling scope. I started off with 3 eggs... two were not fertile and was left with only one. The development was great and my last candling on day 18 showed slight movement. It was day 21 today at noon..... And there was no movement of the egg or pips. I candeled it briefly and saw no movement. Should I be worried? Tips?
