Are these two Speckled Sussex chicks? I have a lot of "chipmunks" so I've narrowed it down as best I could to these two because they have the whiteish/pinkish (not yellow) legs and white on the wings. They are also more brown and chestnut than the ones I believe to be EE and Welsummers. I'm sorry one of the pics is so blurry (hard to keep them still!) but it best shows the white on their wings, so I'm going to throw it in there.
