Advice needed! Bloody egg?

[chipschocolatejet]

I’m a third grade teacher hatching chickens in the classroom. I locked down the incubator yesterday. I went in today to see if there were any early hatchers. When I got there, there were three who had already hatched out and one hatched out while I was there. There was also one who was creating a hole in its egg and peeping. He had not tried to zip yet. When I went back this evening, there were five chickens and the one with the hole in the egg was not moving or making any noise anymore. There was also a lot of liquid around the egg. Can you tell me if this one is stuck or will not hatch? I thought that the liquid was odd. I hatched chickens last year and had one make a hole to hatch but no liquid came out. Thank you for the help! Hoping he is just resting and will hatch out tonight or tomorrow!

He probably busted a blood vessel and probably won’t hatch.

It looks as though it may have pipped below the air cell, hit a blood vessel, and hemorrhaged. Also, the yolk is a sure indicator that the chick is no longer viable and should be removed.

That doesn't look good.
If mine I would remove the egg and check for signs of life. If you think it might be alive, read this article by @Pyxis
