That’s either a rosetta or Tibetan messy tuxedo. The Tibetan have 2 copies of the range pattern gene, and Rosetta has only 1. You’ll see a wide variety, but the Rosetta’s usually have a lot of barring and pencilling on their feathers, with a general lighter coloring, having a range of browns and reds mixed in, so I believe yours is rosetta, but it’s hard to say because lighting can make it look different in different conditions.
That bird is not fee tho, fee is a gene that dilutes the browns and reds. Grau fee is tibetan or rosetta with the fee dilution gene, and appear like black and gray birds with cream and light beige. One copy of fee let’s some browns and reds bleed thru, so you’ll have beige and light orangy colors bleeding thru particularly at the shoulders and upper back. Two copies of fee will create a more uniform black/gray/cream mix with almost no brown and red coming thru. Brown is diluted more than roux, so scarlet/red range, egyptian etc are affected differently, and never dilute to fully white or cream, at best they have a light Cremecicle look. Males that have fee and carry 1 copy of roux will usually show that roux on their necks and backs strongly as chicks and it will fade somewhat as they age.
