2 week old chick bad limp

[big bouncer]

Daisy a very young chick, 1 of 4 hatched by a broody hen, has been following her mother around. Even as she leads them out of the coop and around the yard. She was noticed only using one leg and hopping, so she has spent the last 3 or 4 days inside with us watching her. We feed her and give her water. She will not use her right leg at all. She spends the night in the coop with her mama.

Are her toes curled under if you stand her up? Does she hold her leg up and limp around? She may have suffered an injury, or she may have a leg bone deformity. Curled under toes can be a sign of riboflavin deficiency, so I would add chick vitamins containing ribflavin to her water, or give her 2-3 drops daily of PolyVisol no iron baby vitamins.
