Help~ Why would she be standing this way??

[steffpeck]

I have one of my Barred Rock's that is 15 weeks old is standing weird. She is the one standing in the food bowl. Can someone tell me why she is doing it?

This Blue Wheaten that I had also stood like it to. I did lose her though several weeks ago.

kind of hard to tell..but are her legs weak, and hunched under her?
could you please describe in more detail how she walks?

describe the droppings...color and consistency.
have you given chick vitamins?

are they in with other older chickens?

have they always been on pine shavings?
check the crop..especially in the morning before she eats.
it should be empty, or flat...feel for any lumps or grainy feeling..
is she eating and drinking like normal?

have you checked the vent to make sure it is clear?
