Light brahma sexing??

[Zealo]

I've got two production reds, two light brahmas, and one white barred rock. Now, I was hoping to get all females, because they were already sexed (but of course nothing 100%)... And I've noticed some major difference between my two production red... Was really hoping it was just quick growth.. But one of my PR is definitely a Roo.. However, I can't tell of one of my light brahmas is a rooster.

Other LB for comparison

Reason why I'm wondering why the LB is a Roo is mostly because of personality difference and the tail feathers.
I've only got the other LB to compare with, so I'm not to sure???

Both Light Brahmas look like pullets to me.

Thanks Bantam

I can easily tell between single combs
But the light brahmas are hard for me to tell

Was mostly wondering because of the tail size difference between the two.

I agree.
