Hy-Line Brown is a breed of chicken that was developed in the United States in the early 1960s. It is a crossbreed of several different chicken breeds, including Leghorn, Rhode Island Red, and White Plymouth Rock. Hy-Line Brown chickens are known for their high egg production, with some birds laying over 300 eggs per year.

One of the key features of Hy-Line Brown chickens is their brown feathers, which give them a distinctive appearance. They are also known for their efficient feed conversion, which means that they are able to produce a large number of eggs while using relatively little feed. This makes them a cost-effective choice for commercial egg production.

In addition to their high egg production, Hy-Line Brown chickens are also known for their friendly disposition and good health. They are able to adapt to a variety of climates and environments, making them a popular choice for farmers around the world.
