This is how Brownie looks today. I just recognized that is not stripes on her wrings, it's different layers of feathers. The ends of her feathers has lighter color. She definitely looks like a girl.
Dolly is the one looks suspicious. She has large legs and light barring. But she doesn't act like a boy and had perfect chipmunk patterns.

Both definitely pullets. Unlike Brownie, the autosexing breed pullets have a single barring gene, so you will see white tipping on the feathers. If Dolly was a male she would appear more white than brown. The difference is striking at any age, but the more feathers are grown in, the bigger the difference.
Brownie looks like an partridge pattern of some sort. I wish I understood the genetics that made her that color, I might try to make more like her sometime.
