Urgent Baby bird not walking properly

[Trinketttt]

I had my baby crow ever since he fell out of a large tree, he couldn’t walk and eventually he was able to walk after a while (first picture). My problem now is that he once more isn’t walking properly, only walking with both his feet sideways (second picture). I have no idea what to do, especially if this is permanent, I just want my boy to be happy and healthy

Unfortunately, it looks as if it may be rickets. This is usually seen due to an inadequate diet and/or vitamin supplementation.

Oh gods, is it permanent or can I fix this asap?
