Quail with leg paralysis

[el dorado quail]

Could it be a deficiency? I know https://www.youtube.com/user/Pavlovafowl has some videos about deficiencies and how to treat them might look into the channel

If it seems like she's uncontrollably forcing her legs out straight, she's probably having some kind of seizure.
How often does she have those days where she can't walk? If it's more often than she can walk, I might be inclined to cull. You have to consider if her bad days outweigh the good. If they don't, I'd put her in a sling on the days she can't stand, so she's at least upright.

Most often she cant walk but can still manage to get to her food and water even on those days.

It's not about getting to food and water, it's about functioning as an animal. Being able to hop on things, dustbathe, and otherwise access enrichment, and being able to move around. Think about it- if you were stuck in bed, you wouldn't say you were fine just because someone was bringing you food and water. You wouldn't be terribly happy without anything else to do.
I'd look into chicken wheelchairs and see if maybe something like that could work.
If not, I'd cull.

How mobile IS she? Do you have video?
