No, I am actually against potty training birds. It's one thing to train a dog to hold it for some hours (and I am even against people who work full time having any of the toy breeds precisely because of the housebreaking issue) as a dog would normally defecate 1 or 2 times a day, depending on their size, but birds have a much higher (faster) metabolism and would poop many times a day, sometimes every 20 minutes, and, when they 'go' they do both number one and number two together so training them to 'hold it' is simply unhealthy and I would not risk their health just so I don't have to wipe poop from the floor or a piece of furniture every now and then (I also have 'parrot clothes' -old Tshirts- I wear all day long). I rescue dogs and cats as well as birds so, in my house, hair and poop are part of the 'decoration'
