After shower floor time
We like to sit on the floor after a shower together and just chill
Lately whenever I leave my room (where his cage is) with him on my shoulder he gets hormonal and aggressive. I couldn't get him to do it in the video but he will fly to the ground and follow me on the floor.
He will fly from my shoulder to the floor repeatedly and sometimes will come at my trying to bite me.
This is completely new behavior he is the most handable bird I've ever owned and for the first time in 11 years drew blood last night.
Things I have tried
I got a new cage
Removed toys I noticed he was rubbing on
Swapped out toys
Making sure he goes to bed at 9pm and gets up with me at 6am
I clipped his nails since he gets frustrated when they get to long
Reduced his food
Increased his food
Changed the room his cage is in
I have a second cage now so I might make him sleep in another room
Im out of ideas at this point I will mention he has never been to the vet in the 11 years I've had him
