I would keep up with the vitamins if I where you. I had a chick that had a very bad start and couldn't walk, feet was curled up and all. I did the vitamins and made sure she was hydrated and she did a complete turn about. After a few days she quit eating and slept all the time. I started feeding her a liquidy mash of water, vitamins, starter and a tad bit of sugar. After a few days she was eaating on her own again. Now I give her a little boost every couple of days of vitamins. She is still eating on her own and not sleeping as much. I feel that if I had started her right away on the vitamins she would have done better.
We're tickled too....I have been keeping the vitamins in everyone's water supply but she is no longer dosed with vitamins directly. She walks perfectly fine - you would never know it to look at her now!
