Barred Rock discolored leg

[LvldChickens]

My year old barred rock hen has been hopping around on one foot for a week. It just stays curled in a fist and just hangs there. When she hops, her leg just bobs up and down like a yo-yo. Checked on her yesterday and her foot looks bruised. Checked for black spots or cuts, but found nothing. I've searched this website, but couldn't find a picture that look like hers. She is eating, drinking, and no one is bothering her. Any thoughts???

She could have curled toe paralysis which can be a symptom of a riboflavin (vitamin B 2) deficiency, but could also be a sign of Mareks disease or an injury to her leg causing nerve damage. I would put some poultry vitamins in her water containing riboflavin, and see if that helps. Barred rocks usually have dark coloring up the front of legs, but she looks like there is something on her leg like paint or mud.
