What breed and gender am I?

[chickypoo]

I volunteer at a bird rescue and we have a little chick currently. I am curious to know what his/her breed is.

It looks like either an exchequer leghorn or ancona, both breeds start off white on the bottom and black on top and then start getting more mixed colouring as they mature.

What kind of comb does it have? From the pics, I am inclined to think that its an ancona, but the comb should be a good deciding factor in what breed it is.
