How do you tell if the embryo/chick has died before hatching? (other than a blood ring or an exploding egg) I'm new to this stuff.
As someone also said, candling is a great way if your flashlight is bright enough (try an LED).
Personally when we get to day 15 or so I can tell by the warmth of the egg. If I'm turning or candling, the dead eggs always cool off first and never feel as warm as the live eggs. You can tell by this earlier, but it's harder the earlier in incubation.
I found the full term quitters the other day when removing chicks when I saw no more pips. I candled after feeling the eggs and sure enough, no movement.
Of course I left them in there just in case, though I'vs never had a quitter hatch.

And.... It's a boy!!! My first ever Cream Legbar chick is a little guy! and I will take a picture when he's better fluffed out so I can take him out of the incubator.

No more pips and considering we're somewhere between day 22-23, I'm getting a little nervous about how the remaining eggs are doing. D:
