White dots in my yolks

Ok so I've had these 23 chickens for basically the last year and just recently found little white dots in my eggs I have no rooster well at least i didn't think so none of my chickens crow or have the beautiful tail feathers of a rooster so my question is that the DNA of the hen cause it doesn't look like a bullseye to me or do I have an undercover rooster that just doesn't crow or do anything a rooster would do?

Also just wanna say if I didn't post this in the right spot sorry new user.
