Are you in the States? Baby is more active right now during molting season. They are little freaks, as long as he is fine before and after, I wouldnt sweat it.
Baby gets aggressive and kicks the crap out of everything on his stand so I relate to what you mean.
If youre in the states, that might account for it a bit. I know mine are more 'chaotic' right now... even my tiel. She sings most all day now. Very rare for her.
