Brown Fluid in pipped Ball Python Egg

An egg in my clutch began pipping two days ago so I cut the rest of the clutch. I made sure not to hit any veins. I noticed that all four of the other eggs have a pretty clear fluid in them but one has a brownish fluid in it. Has anyone else ever experienced this.

No, but that sounds likely to be "old blood"- you probably didn't notice when it bled at first, & now that the blood has "aged" it has turned brown.

The brown fluid is in the egg that pipped on its own. I have not cut this one.

Then movement caused a vein to break- either way, nothing else it could be?

It doesn't seem to be moving much. Yesterday it was moving but today I haven't seen any movement. There isn't any kind of foul smell coming from the egg.

Be patient. I'm not one that cuts eggs, btw.
