I assume you are talking about an african grey so here is the truth, pellets do not have to constitute that much of her diet, in fact if they don't get any pellets they can still be healthy if they have a well balanced diet with a variety of foods. A good seed mix to start off with so keep that in the cage at all times then offer lots of vegetable, preferably leafy green ones, you can offer a little fruit a couple of times a week but not every day as it has too much sugar in it, include some grains, legumes, a little pasta from time to time, maybe the equivalent of one egg a week but not all at the same time, some chicken or fish occasionally even a chicken bone from baked chicken, not fried and a little yogurt or cheddar cheese is ok several times a week. Be sure to check out the bird food room for lots of threads with ideas of what to offer and what not to.
