Hello everyone, I am going to to explain to you the way
I am training Jack, my B&G macaw, and again, this is how I do it. Jack is not completely potty trained but he getting close to being there (no bird will ever be 100% potty trained and you must be able to accept some accidents).
Have your bird out on his playstand and just sit around doing something where you can keep looking over at him. Every time you see him get ready to poop (Jack backs his but as far over the edge as possible), say "Go Poop" or whatever phrase you want to use,how about "Bombs Away? Time your bird so you know how often the bird goes poop on average. Just make sure you use one phrase, don't change it around. So you say go poop, and the bird goes poop (it was in the process when you said go poop), so then you give the bird a treat and extra cuddles or attention, maybe some scratches on the head, whatever floats his boat. Do this as much as you can and get him used the phrase "Go Poop" so he knows when you say it, he will automatically go (unless he has nothing to drop).
When you have the bird on you or playing with you out on a couch or your bed or whatever he is on, when you see the signs of him going over to the edge or fidgeting (getting antsey..sp.?) , take him over to his playstand before he poops. As soon as he is on the playstand, say "go poop" and he will because he has to but you will get to the point where he will go because you tell him to, and he will hold it in until you get him somewhere to poop (he will not hold it in forever though, so don't forget that he has to poop when he is playing with you, if he really has to go, he will go). After you have had your bird out with you, keep a close eye on when it is usually the time he would go poop (if your cockatiel goes poop every ten minutes, when ten minutes is coming up, either take the bird to his playstand or wait until you see he needs to go). Then, before you take him out of his cage or off his playstand, say go poop and he should depending on how long you guys have been training and how fast of a learner he is.
*REMEMBER*keep rewarding him with what he wants most/likes best (if it's safe).
Now I can have fun playing with Jack somewhere I would rather not have to clean bird poop off, I am working on training him to go poop even if he isn't on his playstand, I hold him over his playstand and say go poop, that way if we are somewhere without a playstand, he will go anywhere I tell him to.
By the way, if you potty train your bird, you will not have to say go poop to get the bird to poop when he is on his playstand, don't worry about having to say that phrase 4 million times a day.
An additional thing you could do is get a basket with a handle and when your bird has to poop, put him on the handle and say go poop, so the poop will just go in the basket, this way you can just take a basket with you when you go somewhere.
A potty trained bird can make a lot of peoples lives much easier.
so Good Luck to you!
Make sure you tell me how it goes, I will post updates on Jack too.
