Another thought ... check out the fermented feed thread. Supposedly they eat far less using this method. I think I read somewhere something like only a third of dry food. I use it in conjunction with dry and sprouted fodder (wheatberries.) Also, healthy kitchen scraps are a great way to supplement their food, too. I am pretty picky about what scraps I give my 9, soon to be 20, birds, but they can eat just about anything.
