Very cute chick! Does it have feathered feet? If it doesn't have feathered feet I would guess brown Leghorn, but it seems like it might b a bantam. Is it a bantam? If it is a bantam I would think that it is an Old English? I am really not sure but I hope you have good luck with this little cutie! Maybe post again in a few weeks to a month and I may have a better guess.
