Dori is 4 years old. Sometimes, he gets into this weird mood where he drops his wings low, and starts making this sound like "eh, eh." When he does it, he semms like he's throwing a little tantrum and then will sometimes bring food up into his mouth. nothing seems to calm him down--petting, cuddling, kissing...nothing. It almost seems like a sexual behavior, but i think he's too young for that. Any ideas? Paula
