Sounds normal to me. You should see the modifications Rocky has done to our woodwork and the couch and the remote control and the curtains and the mini-blinds and my clothes ...
everything you listed cept the couch and the woodwork.lol
the only problem I have with him is everytime I get him on my hand he runs straight up my arm full flapping and stands on my shoulder and hangs that chopper right next to my face kind of unnerving the first time and all that have followed. to get him off I have to walk to the cage and he gets off there. last time a few days ago I guess I did not get away from the cage fast enough because he very lightly,and gently pinched the back of my arm to get me to move , no marks or anything. I don't think this bird would bite but then again I only know 9 months history out of 15yrs. funny thing is he does not act nothing like that with the wife he sits in her lap to get all that loving and plays on the couch a lot along with the playstand.
could be due to me wanting my wife to be his primary human so I don't handle him to much and he only comes out when she is home. however I'm always playing tug of war and things like that through the cage. also noticed he does not play with her like he plays with me. so I figured at sometime in his life he may have been with another couple that taught him this because it seems so natural for him. he goes to the wife for the cuddling and me for the play.
