Having a bit of a problem with my egg

[Ambray]

Okay sorry it's been so long I kinda got really attached . It didn't end up hatching though it looked like a black silkie with tan feathers, so a splash color, and fully formed too. No clue how it died but I guess mabye it hit a blood vessel trying to get out. I read that somewhere and can't think of anything else. Anyways thanks for the help even if the lil baby didn't hatch I still learned a lot .
