African Grey... Possible crop damage?

Canned vegetables are not good, as one of the other answererers mentioned...but my reason for saying that is not just lack of nutrition, but too much salt. Also, don't use frozen veggies and microwave them, because microwaving destroys so much of the nutrition. A lot of raw veggies is good, as a little well-cooked protein such as beans. I also plan on using some pellet food next month. Now, I feed my 2 year old Congo plenty of fresh veggies like baby carrots, baby spinach, a little fruit like banana, a little nuts and seeds, and even some cooked cereal, with iron, like farina.
