Are you able to change the dish locations? My cage area I cannot... But when Buddy is aggressive I try to either spin the cage orientation, or change or move his toys. This does not stop it completely. It helps a bunch. Also changing the day to day helps, like a bathing day, vrs a normal day. I spend awhile bathing him, some general weekly cage cleaning. Then I bathe, which he is so close to that area of his current room. So, I am constantly going into & out of the room for a few hours. It seems to help some of the boredom I think. I got the idea from a posting I read. I believe it was a JLCribber suggestion but I could be wrong. I just looked All over the threads where *I thought* it was & cannot locate. Sorry!
I know for me reading it in context helps, I will keep my eyes open for it. I'm new to birds so if this is a really bad idea, someone should say. I know my Buddy's issue is directly mating w/ some possible underlying meaness I am trying to work out.
Wish I could be more help!
