I give mine a dry gut that I make myself....I throw a lot of stuff in it...millet,coconut,almonds,bee pollen, flax, baby puffs, Weetabix, cheerios, other stuff I cant remember lol.
I only give them fruits and veggies once a week. (I don't leave it in there all week lol, just two days). The bin that just holds my feeders gets fruit and veg everyday plus the dry. But for my breeder bin its just the dry and fruit once a week. Oranges tend to make them frisky lol
