is this a guinnea egg

Can you get a better picture? That doesn't look like one to me. Guinea eggs are usually very pointy on the small end, and kind of square looking on the big end. That one looks like the big end is pretty well-rounded. But I have found one or two that were really light like that.

Here's a bunch of mine.

They can vary a lot in shade, and a some are not as pointy as the norm. I have some that are markedly larger than others, some much smaller. Jumbo guineas have larger eggs, and some of my feamle are regular and jumbo crossed. They lay some nearly as big as a chicken's egg. If you tap it lightly with your fingernail, it sounds different from a chicken egg.
I think your right, and have a guinea (one n) egg.

I do not think so. They are more triangle like, less long and oval with a very hard shell. But you never know, I have seen strange looking eggs.

Here's more. As you can see, there are some size, shape, and color variations, just like other eggs. Not as much as chickens.
I've had a few I mistook for chicken eggs until I tried to break them open for breakfast. So, looking again at your egg, it's hard to say. If you nearly need a hammer to break it, it's a guinea egg. Tap it with your nail, tap a known chicken egg. They sound different.
