chicks dying during lock-down(in the egg)

[STINNETT]

I have had 23 eggs fully developed die during the 3 lock-down days. Removed the eggs on day 25 and opened them, all of them had fully developed chicks. Had 12 in one bator, 2 hatched and 13 in another bator and none hatched. Never had this happen before.

What could be the cause of this?

I had this problem last year and it was determined it was humidity. I am sorry about your chicks!

I used to have that problem...I live in a really humid area and had to switch to dry incubation.... I've had GREAT hatches this year. Sorry that you are having that problem. I lost all but one out of a close to $100 batch of eggs...
