I have twelve ducks and twenty-five chickens. Both male and female, varied ages, some molting. They free-range, but with winter and all they are likely not getting much. They are on some kind of grower with supplemental, free-choice calcium. Can someone tell me how much food I should be going through a day? A month? How much each? I do not think I am feeding enough. I would like some numbers, be it pounds or cups or whatever. I would also like to know how many feeders and waterers I should have out. Ducks are hogs, of the food and water. I currently have two plain old tractor supply red and white feeders, two waterers of the same style, three pans, and a trough. I have more troughs and such for food if need be. I have four to five black rubber water bowls, a bucket, and two swimming tubs for water as well. Let me know if more information is needed. I would really like to know.
