Are you sure about the Rose Comb? Is this a large fowl chick? In my mind it most resembles a Gold Laced Cochin, but they have a straight comb.
THe breeds that I can think of off the top of my head that have feathered feet: Langshans, Faverolles, Cochin, Brahma, Sultans and some Marans, then (I think) D'Uccles and Sabelpoots. I don't know bantams well so I could be wrong on those.
Of the LF I listed, none have rose combs. The Brahma has a pea comb (which your chick sort of resembles--its pretty close actually) and the Sultans have V (which it does not) and the rest have single combs that I remember. Perhaps its a project breed or one not as common.
Do you have a list of breeds your source was breeding so we can narrow down the guesses a little?
Cute chick!
