Chicken wobbly, falling down, no coordination

[Chickencrossings23]

My 6 week old buff orphington all of a sudden is very wobbly, falling down when walking, and basically uncoordinated. She has been on medicated feed since birth. She has been eating and drinking, I've been giving here vitamin B complex in the water. Does anyone have any idea or suggestions on this? She looks healthy otherwise, her poops look normal, no bad smell or bloody poop. I was thinking maybe a thiamine deficiency, but 2 days on the vitamins and no change. New chicken owner so not sure what to do. I did separate her from the rest of the flock who are all doing great! Any recommendations would be helpful. Thank ya'll!!!

Hi there!

Medicated chicken feed contains Amprolium, which is a Thiamine inhibitor.
I would try giving her some rooster booster orally by syringe until improvement is seen.
It has a higher concentrate of Vitamin B12.
