Ive been wanting to harness train paco but just have not gotten around to getting a harness yet., I just picture him chewing that 40 dollar harness in half in about 3 seconds.
Potty training, that is one thing luckily HE IS. When he has to go he'll kind of flusff up and if I am not paying attention will say my name, when I look over he'll mumble Poo or PooPoo, most the time I catch it and Ill say paco go poo poo? He'll say go poo poo and then I have about 30 seconds to get him somewhere, ie over a garbage can or a cup or something, ill get something under him and say ok, Go Poo Poo. He'll drop his load, Ill say good bird and bring him back to ... whaever was right before that moment., Occasionally he'll let one loose w/o mention but for the most part he tells me, which IS pretty awesome because big birds can leave a nasty mess, especially if you gave them blueberries as treats.
Edit: If he is close to his cage at the time, on occasion he has been known to just climb over to his cage to let loose a deuce, because he's allowed to poop when he is on the cage.
