i am a newcomer in the chickens.i have 9 pullets 1 cockerel RIR/BARRED ROCK,5 RIR hens 3 barred rock hens, 1 bantam rooster and 6 bantam hens what would be the proper amount to feed them in a day? i currently give the 6 cups of starter/layer and 2 cups of whole corn per day plus scrap veggies from the garden. is that about average? to much? to little? or what? all suggestions welcome. i know that most chickens always act like they are starved, but i don't want to under feed them.
