Hi Emma,
Try and find an avian vet ( a vet who specializes in birds ). You mentioned that your parrot is limping and holding her foot up. Even though there was no blood, the fact that your parrot is kind and limping and not using her full strength would indicate to me that her foot did get hurt. If at all possible, try and find an avian vet or a vet who knows about birds. You may have to do some phoning around. We have a cockatiel which is in the parrot family. If that happened to him, I would phone first and explain what happened, how your parrot is behaving . I wish you much luck with this but it sounds like your parrot's foot did get hurt. Otherwise she wouldn't be limping and holding up her foot. I hope my advise has been helpful. Eve
