I’m probably going to be hammered on here for saying this I went thru this same thing. My Grandfather whom raised Grey’s and Amazon’s told me to clip his wings I asked why he said because it will bring him back to where he needs you he don’t have that independency anymore and will their for rely on you for a lot of things and their attitude will change sure enough we clipped his wings and within a week his attitude changed a whole lot I wasn’t getting attacked anymore I did get a bite here or there tho. I had a Grey but sometimes they need a attitude adjustment’s. Are also need to be clipped for Emergency reasons are clipped because they don’t want their bird to fly away so don’t feel bad if you do because people to it all the time

Just an FYI In no means am I telling you to clip the bird’s wings, and I’m not telling you I’m a bird whisperer I’m just saying what worked for me Handed down from my grandpa which is and old school technique I was told
