Your birds look great, Meg200000000!
I need to post a photo of my lighter colored pullet, Iluna, when she is standing up. My other 2 pullets look very much like yours in shape and color. But Iluna is smaller, and has a very weird tail area. Her tail is short and hangs down (not upright). And her feathers in the saddle area are humped up, as though she is wearing a wire hoop under her skirt! Very strange. I thought her shape would change as she grew, but it hasn't really. She's the one on the roost in post 1432, but you can't really see her shape when she is sitting like that.
