This might make sense. In the picture, you can see that there are the egg rollers behind it with some eggs behind it, that are sitting off the ground. If it was sitting there, it could have rolled off the egg rollers and cracked. Its a pretty short distance, but maybe if the egg pipped and had a crack in it, it broke there. Sorry about your egg, AveryIt seems like the egg was dropped from a small height. It's possible that a shell shard caused the chick to bleed.
I hope it can be saved, but that's so much blood.
