6 Week old Wyandotte and Barred Rock-Guess on Gender?? Please!

[Mcclurag]

These two are my questionable chicks at this point....The others all are very much ladies, but these two have me stumped. Males or females? The Wyandotte is slightly larger and stands upright in comparison to the others, but they are all different breed.
Thank you so much for helping a new chicken owner out.

The one on the right looks like male because of it's longer, skinnier, feathers on it's neck. And the one on the left looks like a female because of it's shorter wider feathers.
