What the heck kind of chicken is this?

This chicken has been on here before, but it has changed so much each week, and no one had any real answers the last time. I am pretty sure that it is NOT a sebright. It has a completely different body type than the sebrights I had. This one is long and thin and holds its tail differently than the sebrights. And has a single comb. I have thought that it was a hen because its comb is small and it is not pink at all yet, but I think it looks like it might be getting longer saddle feathers. So that cancels out sebright as well. It is out of the assorted bantam bin at the feed store.





ETA: Nothing wrong with its leg, it is always running away so it looks like it is holding it up.
