Calling all Hatching Experts - opinion on eggshell condition

[SoftBoiled]

This was my first ever hatch, so I'm trying to understand as much as I can after the fact. Below is a picture of the eggshell from the first egg that hatched. The chick had a tiny spot of bloody goop on its bum, smaller than a pencil eraser. The chick hatched itself, although it took a long time to do it (filtered through a great deal of human anxiety it was a long time, but probably about 14 hours from pip to zip).

In addition, the eggshell seems quite bloody - none of the other shells looked like this. Could anyone who is more experienced with hatching fill me in on what happened?

The chick, by the way, seems to be thriving and the little bloody bum thing has disappeared.




Thanks so much in advance

It may have just been a little more wet than the rest.

it is pretty normal looking to me.

Thanks everyone for your input. One of the hazards of being new to hatching - you don't know what "normal" necessarily looks like.
