I think I used Micheals method. Just timed the poops and put him on his perch when that time came. Once he did his business, would praise/remove and repeat next 15-20 minutes. Over time Oscar my

would stop and hop up on my hand when he has to go. I still cant bridge the gap of me having to physically walk him over to his perch to go verses him flying over by himself. But I havent made it a priority in training either. I might start focusing on this more to see how it goes.
