No but treats should not be more than 20% of the diet. 80% of the diet should be pellets like Harrison's. Be sure not to allow him to eat the seeds. They are toxic (contain cyanide).

eat too much apple by: Linda
Yes, they can eat too much apple and become sick. Feed very little apple as it is a fruit that will upset bird's stomach. Feed very little fruit of any kind. Feed organic high quality pellets and only 10-15% fruit and veggies which means small amounts a few times a week. If your bird is sick, you'll have to take it to an Avian Vet.
