Jersey Giants generally are large, gentle birds that have a beautiful iridescent green sheen in the sunlight. Roosters are rarely aggressive, which is great because you don’t want anything that large to be mean! While the roosters can grow to be 15-18 lbs, they are slow growers and do not achieve their full size for two to three years. Hens are not nearly as large, although hens will weigh 8-10 pounds.
 
Hens lay very large brown eggs and are known particularly as good winter layers. Robust and fairly cold hardy.
