Is my rooster a hen?

[Jaron_Green]

Hello, everyone. I got a new batch of baby chickens back in April for our pet flock and I'm loving them. We got a lot of light brahma's and one of them we can't tell if its a rooster or a hen. The evidence for it being a rooster is when it was a tiny baby it would jump and kick at our hands. It also got way bigger way faster than the others and has slightly thicker legs and a thicker beak shape and has a feather saddle. But here's the problem. It also does the submission thing that hens do when we approach and I also found it sitting on a bunch of eggs this morning. I am really confused especially since, judging from the pictures, rooster light brahma look similar to hens. Does anyone know anything about this breed of chicken that I don't and is Mr Chicken a girl?

At 4 months a close-up of the head showing the comb and wattles could be helpful, but by that age a pullet could be pretty well developed. An overall showing the legs and profile could help. What I'd be most interested in would be a close-up saddle and hackle shot. By now these feathers should be either rounded or sharp.
