Jelly bean egg

[LovinThisFarmGirlLife]

Did you open it up?

Fairy, fart, wind, rooster eggs are usually from a tiny piece of tissue breaking loose from the reproductive tract, or an immature ova(yolk) and the body forms an egg around it. Color can be darker than 'normal' as the pigment coating released has to cover a much smaller area so is thicker. Can happen with any age layer.
Think it's explained in this excellent video
Egg Formation Video
(which is worth watching even if it's not explained)

I didn’t open it but I did blow it. Just egg whites! We have s chicken who consistently lays those dark colored eggs so I assumed it was her sister. I would love to watch thy video but the link didn’t work

Bummer, thanks for letting me know, will try to fix it.
Looks like it's been removed from the Auburn University website
