Since your little guy is just learning to eat his adult diet, he is picking the easiest thing to eat. I’m not sure what his “nutritional mix” is, but typically a mix with loose seeds is not going to be as balanced as other diets. Most seeds are not very fresh once they make it to the shelves, and unless the seeds are hulled, any added vitamins are lost when the bird hulls the seed. I would recommend our Nutri-Berries and Avi-Cakes. These are nutritionally balanced the same as a pellet, but they are not ground up. They contain fresh, hulled seeds with other fresh ingredients and provide the whole seeds and foraging exercise that are more like his natural diet. You can feed these along with or instead of pellets and he will be getting complete nutrition. His chop diet will round everything out, but you can offer fresh veggies and fruits sometimes, too.
Here is a link to our feeding guide with more information:
