I had a hen that had a bad limp she would limp and then just lay down. I put her in a cage and fed her a vitamin B complex crushed on scrambled egg plus her feed every day for 7 or 8 days after she could walk but still limped kept giving her the B complex every other day now I give her 1/2 tab of B complex every other day, I stopped giving her any after a month acouple of days later she was limping again so I started it up again, it has been 2 months and now she isn't limping at all, but we still call her Limpy
