For pellets my ekkie is on roudybush rice diet with some Zupreem Natural and nutriberries as treats (she go nuts over them). I haven't had problems with toe-tapping or wing flipping AND she has almost stopped plucking. But it's good to remember some ekkies are more sensitive to pelleted diets, especially to Harrison's which contains spirulina.
I also have her on a bean/brown rice/whole wheat pasta mix. This is so she gets the fiber and protein she needs without having to feed primarily pellets. Ekkies also require fresh fruit everyday, preferably one high in water and fiber (like melons)
I follow this diet
http://landofvos.com/articles/mydiet.html pretty closely, but add the pellets so she can have food in her dish while I am at work.
All my birds eat this but in different ratios. Conures get more pellets, little bean mix, and some fruits and veggies. Scarlet gets more bean mix, extra fruits and veggies, little pellets.
Good luck!
