ChiX is the collective name for chicken feeds. “The X-line” makes a distinction between chickens, bantam hens and large fowl.
Chicks need lot of energy and building blocks for a smooth and balanced growth.
Bantam hens are smaller in size and therefore need feeds that are easy to digest.
-As you'd expect from the name, large fowl consume a large amount of feed. These breeds therefore have a requirement pattern where adequate proteins and fats are a top priority.
