[2]: 28 [3] Harry S. Lamon was the senior poultry expert of the Bureau of Animal Industry of the U.S. Department of Agriculture.

From 1912, working at the Henry A. Wallace Beltsville Agricultural Research Center in Beltsville, Maryland, he crossed white Plymouth Rocks, silver-gray Dorkings and white Leghorns to produce a breed with good egg-laying capabilities which would – unlike most layer breeds – also provide a moderately tender carcase when its laying career was over.

They have yellow skin and white plumage, which makes them ideal meat birds for the U.S. market.

They have single combs and – unlike other breeds that lay white eggs – red earlobes.

[4]: 54  Unlike most layer hens, Lamonas remain moderately tender as a meat bird after their laying career is over.
