Reading from an avian breeder's website near me says that potty training can be done in as little a 72 hours and that it is a myth that it will hurt the bird because the bird holds it in, since the bird is taught to poop on command, not NOT poop when it isn't told. This site offers an information packet for purchase on how to train step for step.
The bird diaper says it keeps a parrot clean undereath because of the deep pocket, and that the suit fits comfortably on the bird.
Obviously both people are trying to sell me something, so I'm wondering from bird owners I can trust not trying to sell anything, just wanting best for the bird, which is better? Or are they both rip offs? Have you personally tried either of these techniques or do you not believe in potty training your bird?
I personally figure if a bird can be trained to do so many tricks, potty training would be the most useful trick of all.
