I took the egg apart. No obvious signs (to me) of what went wrong. The membrane was not sticking to any part of the chick. No especially bloody parts.
The yellowish liquid did not look bloody, though a bit of red blood could easily have been what gave it a bit of a brownish appearance. There was no pool of it in the egg. But, my guess would have to be that the chick drowned in the liquid as the liquid was escaping the egg.
