Sexing Barred Plymouth Rock Chicks - Please Help!

[amib]

I have 2 barred plymouth rock chicks. They are 3 weeks old today. The first set of pictures is Scout. I suspect Scout is a roo, but an hoping and praying not. I already have a rooster and can't have another (I only have 5 hens).
Can someone please help me?
Here are the pictures.

Scout (barred plymouth #1)










Phoebe (2nd barred plymouth rock)









As you can see, the 2nd chick has much more tail feather growth (just like the golden laced wyandotte I have that is also 3 weeks old). Their combs aren't much different and I don't see a difference in their legs or feet.

Please help! If one is a roo I need to find a home for him ASAP!

Chick 1 & 2 IMHO are males. Although I am more unsure about #2

If I am wrong I plead that it's still to soon to tell.
