I see from your other post you have found a new pellet,good luck with that.
Here is the ingredients that are in my seed mix i feed my greys,they get this along side,veggies,pulses,fruit & a tropical soak mix ( papaya,mango,coconut,water shrimp,banana,pineapple etc ) they have in the mornings.
you dont have to feed nuts,try something like grapes for a treat .
