You didn't mention the brand of either the old food nor the new food. Knowing that would be helpful.
Perhaps your budgie does not like the taste of the new food. I would get a small amount of the old brand to ensure your bird has enough to eat.
Please post the brands and nutritional information of both the old and new and we can try to advise you from there.
