Off balance chicken

[Sakwa_th]

One of our roosters can't walk properly, they can move their legs but they lean more on the back side/knee. When he goes to move his head sways a lot, kind of like how an owl moves it's head. It's been raining a lot recently and the roof they had leaks so the ground was not optimal, (we fixed this today luckily) so maybe he slipped? His feet look ok so I don't believe it's bumble foot. It could be a vitamin deficiency, the other chickens don't have this issue though. Any ideas on what it could be?

Wry neck, aka vitamin deficiency.
Give 400i.u vitamin E and about a third B complex tablet every day for a few weeks
You can get these at the grocery store

Which ones should I get for chickens, or are any ok as long as it's the right dosage?

Any are OK, vitamins are vitamins.
