Why does your parrot eat his poop?

Your parrot will eat his or hers poo for certain reasons. One of which is that there poop is full with nutrition because of what they eat. A parrot eats the following nuts, seeds and grains, and fruits and veggies, and all those foods are full with vitamins and when they eat they normally they don't get all the nutrition so they eat it in poo form to get the nutrition they did not get earlier. Just like hamsters, rats, mice, bunnies, and others in the rodent family.

It could be possible that he isn't getting enough minerals, try adding some pellets to his diet.
