Hatched chicks pipping other eggs

[possumblossum]

Twelve RIR's hatched out over night. This morning I was cleaning out the old egg shells and when I picked up a shell fragment there was an dead chick under it. It appears the chick stopped developing about day 16 or 17 because its eyes didn't finish forming and the yolk had not been enveloped. The shell fragment that it was under was cracked perfectly around the middle, from end to end. This gives me the impression that one of the other chicks pipped it from the outside.

Is this a feasible deduction? If so, is it common?

Thanks,
Justin
