Grayish spot attached to egg yolk

[BaileyPoole]

Hey everyone! Just curious what this could be? My first thought was a tiny little embryo but I pick up their eggs every day. It has like a white spiral attached to it.
*Edit- I’ve read about meat spots but didn’t think they looked like this. I could be wrong.

They could possibly have worms. Buy a dewormer for them.

Most likely a little bit of meat from their reproductive tract. As long as they're acting fine, and not doing it often, I'd leave them be.
