The link above is to a video of one of my baby chicks. She can walk fine when in small areas eating but when he mother goes acrossed the yard she can not keep up long distances. Her legs get really elongated and her feet starting going backwards the faster she walks so then she'll use her wings to try and keep balance but just ends up sitting down and resting a few seconds then she starts again. Has anyone have any idea what could cause this? The other 8 babies are fine.
