I'm still learning which foods Emmett likes and dislikes. It seems he throws a lot out of his bowl and some is left uneaten. I offer a combination of fresh fruits & vegetables mixed with something such as cooked oatmeal or wild rice.
What size portions do you feed your Eclectus?
I find if i chop all fruit & veg in small cube size pieces, about the same size as the frozen carrot cubes. I also put my eccies food in a medium ceramic dog bowl on the floor of their cage. I also have to place a newspaper under the bowl so the food doesn't fall through the grate. It does take eccies awhile to learn how to hold their food in their foot to eat.
Try him with some sprouts in the mix as well. A good serving spoon about the size of a small soup ladle should be plenty each meal. There is some times a bit of wastage with these birds. They tend to leave a bowl of mush after they are finished chewing it all to a pulp. If you think there is to much wastage cut back on what you give him. As a rule of thumb give him enough food that he will consume in 1 hour. He will let you know when he's hungry. My lot call when the dish is empty. You get to know when they have run out of something.
