Wondering about breed

[apryl]

I bought my first chicks at a local farm supply store. They were labeled "straight run chicks" (nothing else) at that time I didn't have a clue what that meant. We got 6 of them, lost 3 (1 to a cat, 1 to the duck pool, and 1 to unknown causes before it was a week old) They are now 16 wks old. 2 of the 3 are roosters.

This is what they looked like when we got them:

and this is what they look like now:

Any idea what they may be? They are mainly the cream/whitish color, but have brown spots on them.
