Chicks unable to walk!!

[Crinixx]

I have 4 newly hatched chicks, they're around 3 weeks of age. Two of the chicks appear to be unable to walk, one was already struggling and the other started showing signs of being unable to walk. They shouldn't be injured. When they attempy to walk they simply move their legs from side to side (like a deer learning to walk) and im unsure what to do. I started feeding them yogurt, maybe its a riboflavin deficiency? If not, i need help on what to do next, i am not a begginer to new hatchlings but this has never happened to me before. All help is appreciated!

Are they on chick starter?

Did they seem normal after hatch?

Yes, chick starter and one was a bit wobbly at birth, the other started wobbling a little after

Photos of brooder?

I'd start giving them all B-Complex. Crush up a B-Complex tablet, mix it with a bit of wet feed and let all 4 chicks eat the mash.

Do you normally give your chicks yogurt? It won't necessarily hurt them, but a small amount will be sufficient.

They were all walking o.k. (ish) for the last 3 weeks or has this progressively been getting worse?
Chick starter is "fresh" and in date?

Just trying to think what may be happening. You've had chicks before with no problems. Are these from your own eggs, purchased or?
