Carbohydrates of Amrock chickens can come from a variety of grains, oats, wheat bran, etc. They also need to consume fiber from various boiled and chopped vegetables like potatoes, carrots, etc.

If you keep a mixed flock including both roosters and hens, it would be better to use boilers’ all-purpose feed. It will give enough protein content and the right amount of calcium for all the flock.

Since Amrock hens will demand higher protein and calcium contents during their laying egg to enhance their productivity and make the eggshells sturdier, you can give them a separate diet.
