Eggs 10 months old

[hollycham]

Hello I have a question if anyone could help me out.... My eggs will be ten months old next week and none are hatching... I have lost half of them and most just recently they sweat for a day or two and then nothing comes out but they quit sweating and then die??????
Should I start helping these little guys break out after a day of sweating?
I opened one after this happened and the little guy was all formed ( but the egg had sweated for two days and then nothing came out and it starting shrinking and shriveling up and getting soft

I think we might need some clues first.

Species? Incubation temps? For mom: Prey items, insect gut load type and supplementation brands and frequency?

Be as accurate as you can and you will get betters answers.

HOw much moisture is in your lay bin??
Sometimes if the egg is too dry, they cant break through.
