What to know about Sapphire Gems

The Sapphire Gem is a hatchery hybrid sold by several US hatcheries. Its exact background is not fully published, and you will see different stories about where it came from. Most sources describe it as a Plymouth Rock based layer from European stock. What keepers agree on is the result, a soft blue-gray or lavender-gray hen that lays a lot of brown eggs.

Sex-linked chicks

Sapphire Gems are sold as sex-linked. Female chicks hatch in a solid blue-gray color, while males hatch with barring and grow into barred birds. That is why most people can order them as pullets and get what they expect.

Day to day

Owners usually describe Sapphire Gems as calm, friendly and active. They forage well, handle confinement, and fit easily into mixed flocks. They are medium-sized, a little lighter than heavy heritage breeds, and do not fly much.

Laying and climate

Expect a good number of medium to large brown eggs. They are said to lay fairly well through winter. They are rarely broody. Like other production birds, their best laying years are the first two. They cope well with cold and heat, though large single combs need watching in deep cold.

Plumage notes

The blue-gray color is not identical from bird to bird. Some are darker slate, some more silvery. Since it is a hybrid, breeding two Sapphire Gems together will not give you more Sapphire Gems.

How they compare

The Sapphire Gem vs Olive Egger comparison is useful if you are weighing pretty feathers against colorful eggs. If you want a heritage barred bird that breeds true, the Plymouth Rock is a good choice.
