Help sexing my Salmon Faverolle chicks?

[Bethany101]

#5 is a girl.

1,2,3,4,6
All boys

Here's some update pictures I just took for you!

#2, who had massive wing feathers. The baby photos did not capture how big his wings were compared to the others. He developed much faster than all the others.

And #5, the only girl from the hatch. I think she's turning out lovely, but quite quite the scaredy chicken.
