Some of the posts recommend chopping up smaller than large bird size pieces. Personally, I like feeding my Cherry-headed conure (a little smaller than adult BCC, usually) large pieces of fruit and veggies sometimes. I think it is good way to offer a type of foraging that is different than finding hidden or hard-to-get-at foods. Pritti has no problem figured out how to get into a whole organic apple and what he feels like, same with peeled cucumber, broccoli, sugar snap peas, pears, corn on cob, etc. etc. I don't always do it that way, just once in a while. Other times they are small chop, and other times they are larger wedges too. Keep foods and sizes varied is my 2 cents.
