14 oz every 3-4 months, eh? That's pretty good.
You say the chickens are almost paying for their pellets. Why don't you check out some of the threads on fermented feeds? People who ferment their chicken feed say their chickens produce more on less food since they digest it better. Maybe if you did that your birds really would pay for their pellets. It can be given to ducks and quail too- probably turkeys as well.
You're raising several species, that must keep you really busy!
You are the second person who has mentioned fermented feed...... I will definitely look at those threads.
