Where did you get the chick? It will help narrow down the possibilities. The color of the chick when grown will likely be mottled with possible what I call reverse barring.
Where did you get it? From a hatchery, which hatchery? From a feed store, can you see what breeds might be a possibility or which hatchery it came from. If you got it from an individual then we can't really know what it is, it could be a mix as easily as a breed.
Looks a lot like my Mottled Ancona chicks did, so I'm guessing something black & mottled, with clean legs
Exchequer Leghorn is another possibility. Look very similar to Mottled Ancona
The white/yellow parts likely will mostly turn black, and if mottled you'll start to see white dots coming in
