I would never ever, ever give Archie any kind of animal product, eggs, bones or meat. I am a vegetarian but that wouldn't stop me feeding meat if I thought it was necessary as I prepare raw meat (yuck) for my dog...bones, ofal and all. However as someone else said, giving bird products to a parrot seems to border on cannibalism!
There is so much equivalent nutrients in other foods that I think that if the bird has a thoroughly well rounded diet there is no need. I think fresh, sprouted and varied is vital and as little cooked as you can get away with.
I should add that being vegetarian has caused me to do quite a bit of research on nutritional info for myself, such as where do you get your B vits so I have just applied the same to Archie. Tahnini and sesame is high in calcium I believe so he gets that mixed in with his veg/quinoa mix.
Besides I really don't think I could take kisses from Archie after he had been snacking on a chicken bone!
