you should take her to a vet, if she is still acting that way, keep an eye on her, of course if you were at the vet then she may be pregnant, have you left her with a male recently?how old is she, if she is 6-8 weeks olds and lost quills, adult ones could be poking up and disturbing her, how would you feel if you and prickly hairs growing from your head?
just make sure to regulate her heat and make sure she has everything she needs to make her happy
