Chick is having a seizure

[ILoveBabyChicks00994]

My chick is 13 days old, she's been always fine and way active but today she was kinda standing weirdly, I watched her for a while she fell on her side and starting moving her head frantically and couldn't stand up any idea what that is ?? It's the first time I have seen a chick doing this and I really have no idea what's happening, she's also shiverin

Might she have suffered a blow to the head ?

She got a very little blow to the head on cardboard yesterday, but she has been acting normal since until now. Could that be it??
