Curled up toes

[Niss]

This AM I found a leghorn had taken over my broody box. She was still sleeping, but did wake and was fairly alert from that piont on. I moved her out and she fought me just a little (less than normal). The one foot is curled up and cooler than normal (although last night was cool). Does it sound like riboflavin deficancy? I accidently perchaced 1,600# of wheat and have been throwing them quite a bit of that (in addition to where I was trying to fill in my lawn and they scratched it up

). When i get home I will add yeast to their food. Assuming she's still alive, is there any treat that would work to fix her up? Any other messures I should try? Am I on the wrong path?

Thank you!
