Crooked butt?

[Darklingstorm]

My little EE (chocolate by name) has what I can only describe as a crooked butt. Not sure if its a hen or roo yet. Chocolate is 9 weeks old. I've looked chocolate over and there are no mites and to my knowledge no injuries. Got Chocolate at a feed store where I got all the rest and they are fine. Is there something wrong with it or is it just her/him.

It's wry tail.

Looks like a hatch defect. Is the spine twisted at all or just the feathers growing in oddly? I am guessing from the pics that there is a spinal defect like scoliosis.

ARGH! Sorry. Double post. Computer is wonky this morning.

He/she won't sit still long enough to examine very closely. Heck it took me several days just to be able to get a good picture. If it turns out to be a roo then he will get replaced. If its a hen then I won't be hatching her eggs out. she is my only EE so distinguishing her eggs from the rest will be easy.
