I'm thinking it's likely an Easter Egger, because I can't find many other possibilities.
The dark legs would be wrong for a Brown Leghorn, a Welsummer, a Barnevelder, and most others that hatch with stripes like that.
It "could" be an Indian Red Jungle Fowl, but I just don't expect to find those in most stores! I know there are a few hatcheries that sell them (really, something domesticated that looks like them), but I think Easter Egger is much more likely.
If you post photos again in a few weeks, someone may be able to figure out the breed.
Also in a few weeks, it will probably be possible to check the gender by the feather colors: a male will likely grow black feathers on his chest, while a female will grow brown or tan or salmon-colored chest feathers. (That's true for most but not all breeds that hatch out that color. Black chest reliably indicates a male, but brown chest is only mostly-accurate at identifying a female.)
As for what color eggs the chicken could produce, you'll only know for sure when you see them!
