RIR Chicks to big to get out of shell

[lilmac1990]

Hi all this is my third hatch, and ive been pretty successful so far I feel but today I had a chick hatch completely and expire within a minute of pushing out of the egg. It was quite a big chick could it have died from pure stress of the hatch? Or could be other factors like humidity to high? Any input is greatly appreciated!

this is the chick in question.
