What's wrong with my 3 week old chick?

[Mitchell Farm]

I am raising 26 chicks at this time. As I was watching them this evening, I noticed one of my little Australorps having difficulty walking. She almost acted as if she was drunk wobbling side to side and squatting as she walked almost as though she didnt have strength to stand upright on her legs. She is still eating and drinking, but struggles to walk as a "normal" chick does. Any ideas as to what might be happening? All others seem quite healthy.

maybe splayed legs or crooked toes? Check her toes and legs to see. Is she drooping her head or is it up right and attentive as the others? If it's drooping any could be cocci possibly?

Her head is upright, though not elongated as the others. I have watched her all day. She comes waddling quickly to eat meal worms or scratch and she seems to be holding her own with the others. Eating and drinking well....may just be as you said,,,she does appear to have splayed legs. Thanks for the input!
