4/6 chicks stopped developing and they all died what the heck

[Mr.Grantly]

ok after reading through the forum again heres some things I think I did wrong.

Forgot to turn the auto turner off and they where turning until day 21
Opened the lid to "check things out " up to day 20 noticed that a chick had made a small hole in the shell. (he was the only chick to survive out of 6).
Thought I would save a chick that had made a small hole and wasn't doing anything after that for 8 hours and killed him
the wet bulb from day one even with very little water in the bottom read something like 92

The other 4 chicks had been moving before day 22 and after day 23 I opend them all up and they where all dead at the same stage?
Anyone else have this problem with the turn x tx6 and the wet bulb reading hight?
why do you think they all stalled out at the same stage of development

Thanks for all your help

Grant

one of two things. humidity to high or humidity to low. Only one piping the shell makes me think to high(drowning) But it could have been to dry an they just couldn't hatch an died of exhaustion. Hard to say for sure but it is a humidity Issue.
