She almost looks like a Blue Copper Marans... maybe a mix like that? Leg color and whether they are feathered or not would help... she's a gorgeous blue though!
Btw, many people who sell their eggs for eating don't like to keep broody prone hens... nothing wrong with them, just some like to hatch more than lay... she looks fine and healthy too!
Or she could be a blue copper maran.... probably most likely
