Thanks for the photos and video.edit: during the day she is out on my bed on a shirt/ towel so she can run around and excerise her legs/wings. i dont keep her in her bed all day lol
The noise she's making is a comfort sound that chicks make, it's sweet.
I would place her on a hard surface like the floor instead on the bed. Place puppy pads on the floor to catch droppings and let her move around on a nice firm surface to exercise her legs. The bed and shirt/towel may be a bit too soft to get a good balance.
Do you notice if her legs are bowed or crooked? Can you get some photos of her standing on her own so we can see the position of her legs?
It wouldn't hurt to give her B-Complex daily to help with leg health. You can find the vitamin at Walmart, CVS, etc. Give her 1/4 tablet daily.
