Is this part of an egg from some kind of species long ago or just a rock?

Welcome to TFF!

Thanks for posting pictures here.

This rock is not a egg or any type of fossil.

It looks like a chert nodule.

If this still had the other half connected to it, it would be the size and shape of say a football... Are chert nodules normally that large?

You can have nodules of many sizes, some much larger than that. Many are vaguely egg-shaped.

A concretion of silica dioxide (SiO2) a cryptocrystalline quartz mineral.

They form in sedimentary rocks, and can get quite large.

All this time, I finally get answers about what it is. But it totally looks like a giant egg! Even has cracks and missing chunks on it's thin, outer surface just like an egg would have. Well thank you all for your answers!

When a cryptocrystalline quartz is exposed to the weather the silica will bond with water at the surface. The longer it is exposed the more hydration occurs. This will form a shell like layer on the rock.
