Any way to tell for sure sex of barred rock chicks?

I got 10 straight run from TSC about two weeks ago. I did the whole legs up or down trick, an as of now (although early) there are two that are a little lighter than the rest. However there are 4 with short tail including the ones that are lighter. Now I will say that the legs up or down trick led me to believe that there were 2 cockerels and 8 pullets. Sound like its about right with the color it would the tails be the better indicator? They are two weeks old....ish. Hard to tell when u but them from a store like that.

A good way of finding out is the roosters develop wattles and combs much faster. Also, hens develop feathers faster. This is not totally accurate but is a pretty good way of finding out.
