Please help! Strange Conure behavior and a biting problem too.

Hi Everyone, I have an 8 week old GC who is usually very sweet. We spend a lot of time with her and she receives tons of affection and attention. However, she can be ridiculously moody and sometimes she will seem to have these little "attacks" by herself in her cage by screeching a little (not a lot) and sort of allow herself to fall down on her side and almost contort her body and end up on her back sometimes and usually chews on her foot or grabs her face with her foot. She seems agitated when she does this. This isn't limited to the cage. I'm concerned because I can't find any info on this behavior anywhere. Is she just being a moody weird conure or has anyone had experience with this? I hate to drop 250 on a vet visit when she's eating well, generally very playful, happy and well adjusted otherwise. Also, she's going through a definite biting phase. Not nippy. I haven't figured out how to deal with this. Saying No in a firm voice and giving her the evil eye doesn't work. Any advice other than just wait it out???? I could use the help. She's my first conure.

Why the repeated messages?

Are you sure she seems agitated? When my birds grab their heads with their feet or chew on it, their scratching and just reliving some of the itch. As for the falling down part, that comes naturally with a conure, LOL. They like to fall and sleep on their backs.

SB, Sorry! Still figuring out the forum thing.
Apatrimo: You were right. She was just fine. She throws little temper tantrums and it's just part of being a baby GC Conure. Thanks for your reply!
