How many cups of food should 9 laying chickens, who don't free range, eat per day? I am trying to figure out if my ladies are eating quite a lot, or if we are feeding the rats. I was thinking of trying to just feed in the morning instead of leaving a feeder in the coop, but not sure how much to give them. The breeds I have are barred rock, australorp, buff orpington, red star, wyandotte, brahma, and 3 easter eggers. They are 27 weeks and laying about 5-6 eggs/day.
