I have one of those little flying saucer incubators with 4 eggs in it. Only one developed. It's now day 23 and I haven't seen it move for a few days. (Candled) Is it just out of room or is it dead? I hear too many people say they opened an egg thinking it was dead, only to find it alive.... How can I tell? How much longer should I wait? What would cause it to die in the egg after developing so well? He's the only little guy to make it this far... I really want him to make it.
