Strange behavior and strange egg. Can anyone tell me what's happened?

[Daisycar]

Hi everybody, I'm an Italian member, first of all forgive my bad English, I'll try to do the best to explain my doubts.
Yesterday one of my exbatts had a strange behaviour: she was laying on the soil - where she never layed an egg - and it seems she was trying to do it. She remained in this position more then 30 minutes, she even didn't to go freerange with the others. I supposed I would find a soft egg this morning, but I found instead a little round egg in the nesting box, but I don't know who has layed it. In the attachments you will find the video and a pic of the egg. If anybody could help me to understand I will be very grateful. Thank you in advance!

I don’t know about how the hen was acting, but that little egg is called a fairy egg, or sometimes a fart egg. It happens, and it’s fairly common.

I'm sorry, I'm not able to attach the video. Here's some screenshots, hoping would be useful ...

Fairy egg, what a nice word!
Thank you @sloanbychoice for teaching me!

Your english is excellent.
Videos have to be uploaded to youtube, or a similar platform, then linked here.
She may have had trouble passing such a small egg, like happens with softies, thus the odd behavior.

What was inside the small egg?

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, but more common with new or older layers.

I think it's explained in this excellent video, which is worth watching regardless:

Thank you so much for your kind replay and explanations. And for the tips to attach videos too.
I didn't open the egg yet, it is so nice that I don't have the courage to break it..I'll do in the next few days.
The video is very interesting, I appreciated it very much, thank you for sharing . Have a nice day!
