This is Sweet Brown. She (I think?) is about 15 weeks old. She was with her brother who at 8 weeks old crowed and is most definitely a cockerel. However, Sweet Brown has beat up her brother more than once. She has never crowed to my knowledge but is quite mean to other chickens, has very pretty tail plumage and is a good size. She does not have any spur nubs and her comb is quite pale compared to her brother's. So, I am at a loss, I would like to either integrate her, or if she's a boy, find a new home or something. Thank you for your help. 
Todays picture.
At about seven weeks old I'm guessing.
Here she is with her brother.
