It wasn't clear from your first post that you were giving the rice and scratch mix to the chickens as well. I have no idea how much a quart is (metric here) but you talked about cooking up 3 pounds of rice and a quart of scratch and giving them a 'big portion every morning' and the whole batch lasts a week. I can't visualise the portions there. But you did mention the price of the rice so it looks like you are trying to save money by feeding it.
I stand by my advice to not feed the rice and scratch mix every day, or at all. It gives them nothing but empty calories.
