Why is my budgie eating its poop?
There is nothing wrong with your birds and they are acting quite normally and they don't have a dietary deficiency.
Budgies have very short digestive tracts. Because many vitamins and minerals are fairly complex the birds cannot obtain the full benefit from them when they eat them. They then eat their droppings which contain partly digested vitamins and minerals to obtain the full benefit of them.
Humans and most mammals have long digestive tracts and can utilize the vitamins and minerals fully before they are excreted out. Birds cannot do this especially considering most vitamins and minerals are fairly complex.
You may not like it but it is very normal and natural for them to eat their droppings and will not harm them at all, in fact it is doing them a lot of good.
I saw a lecture on this when I first joined the Budgerigar Society back in 1993 given by one of our best Avian Vets, Mike Cannon. Not only is he an Avian Vet but he is a breeder himself breeding many varieties of parrots. He is also a qualified Exotic Vet and teaches trainee vets at University.
Mike and I have spoken many times on bird nutrition as he has now become a friend.
One of the worst species I have found to do it is the Sun Conure and Cockatiels do it regularly too. Not all birds seem to do it but that may be just because I haven't noticed.
Many of the books written about birds and particularly budgies are wrong in a lot of their statements. Many were written many years ago when very little was known about bird nutrition. And I think the latter books were just basically copies of the older books. People just cashing in of a cash cow.
