Unique Colors

Sapphire Gem chicken feathers have a blue-to-lavender color, hence the name Gem. Both genders are mostly blueish with light and dark gray feathering. Some refer to them as a lavender chicken.

Their coloring is due to the Dominate Blue gene when they were crossbred with Blue Plymouth Rock and Barred Plymouth Rock breeds. Their feathering is ornate and makes them distinct. 

A Sapphire Gem rooster will most likely have a white dot on his head. Adult males appear mostly blue and often have some barring. Hens will have a grey or golden-like ring around her neck. 

Note, Sapphire Splash chickens sport a mixture of varying shades of gray plumage with some specks of dark feathers.


This chicken stands more upright and has an upright appearance. It’s similar to Plymouth Rock chickens in this regard. It is a medium-sized bird with a single comb on top of its head, which serves many purposes.

At maturity, they weigh:

  • Cocks weigh 5 – 7 pounds
  • Females 4 – 6 pounds

These chickens have single combs. Small combs can indicate the pullet isn’t mature yet to lay eggs. The Sapphire Gem rooster’s comb assists with attracting a mate. The comb of a rooster is large and noticeable to show females that they can produce healthy offspring. A hen’s comb is smaller but still just as attractive to a rooster.

A normal comb for most breeds is most likely red, purple, or black. If you touch the chicken’s comb you will notice the soft, elastic feel that indicates the chicken is healthy. 


Unlike many chickens, Sapphire Blue Plymouth Rock’s are docile and quiet. They are among the best chicken breeds to raise in your backyard. They like to receive attention from their owners, which makes them great pets. If you are looking for a lap chicken, look no further. 

They also get along well with other breeds though they tend to be lower in the pecking order because they aren’t aggressive. Keep predators at bay by providing a secure and safe coop and chicken run space.

Sapphire Gem chickens like to have their space. Be sure you have four square feet per chicken. The more space, the healthier and happier all the chickens will be. It’s important to provide opportunities for fresh air, sunlight, an area for dust baths, and areas to forage and explore. This will keep them active and busy. There are chicken toys available to prevent boredom. 

Free-ranging your chickens is acceptable all year long, but they do not peck in the snow. They need to stay in the coop during wintertime (snow, sleet, etc.) so they can eat and stay warm and dry.

Sapphire Gem Chicken Eggs

Aside from their beautiful plumage and their friendly temperament, these hens are often sought out for their egg laying capabilities. They are high producers.


The Sapphire Gem is well-known for its egg production, which is one of its most renowned features. Hens can produce eggs year-round, and they’re known to lay up to 300 eggs per year. They are considered to be among the best egg laying chickens

Sapphire Gem’s begin producing the large brown eggs between 18 and 24 weeks old, and they lay roughly four to five eggs per week. Like many hens, their production will begin to taper off once they are two years old. After this time, they will still lay eggs but there won’t be as many. 

Though they do prefer warm climates, they are extremely hardy and do well in cold weather. Their egg production will not be altered by the changes in temperature. This makes them ideal for colder regions as often will lay year round.   

Chicken enthusiasts may want to add these to your brood if you have girls who don’t lay in the colder months. Provide chicken nesting boxes and places to roost.

These hybrid chickens are a medium-sized breed. They aren’t usually raised as a meat chicken because of their medium size and the fact that they are superior for egg production. However, there is a decent amount of meat on them. 

Once egg production stops, it makes sense to consider if you want to keep them as pets or use them for meat. It depends for your purpose for raising chickens on your homestead. 

Breeding Sapphire Gem Chickens 

Gems are very close to the Old Andalusians. If you are looking to breed Sapphire Gems, it’s important to know, when coupling the rooster and hens, their offspring may not be a Sapphire Gem. Being a cross between heritage and hybrid chickens, they don’t breed true like other chickens.

If they hatch true and you have Sapphire Gem chicks, determining their gender is somewhat easy because they are a sex-linked chicken variety. Soon after they hatch, you can look for different coloring between the males and females.

Sapphire Gem female chicks are typically solid blue or tinged lavender. Male chicks typically will have a white spot on their heads or on their wings. 

When buying chicks, like with most breeds, the males will be less expensive than the females. Unsexed chickens will be priced in the middle.

How Sapphire Gem Chickens Tolerate Temperature

Sapphire Gems are both heat tolerant and cold tolerant. They flourish best in warmer weather but still need good shade and plenty of water. In addition to having a well-ventilated living space, providing fans in the coop will help cool them off too. There are many ways to keep chickens cool in the summer heat.

Some chicken farmers place blocks of ice near them so they can drink the water as it melts. You can also set out a small wading pool about 4″ deep. They can stand in it to keep cool. 

Make sure your chickens have adequate shelter during bitterly cold weather as they are vulnerable to frostbite. Keeping roosters and hens warm and dry during cold winters is essential.

Their combs can freeze and fall off if you do not protect them. Putting Vaseline on the combs may provide some protection. Special coop heaters are available and may be an option.

A chicken’s comb is like an external organ that plays different roles. One of them is to regulate body temperature.

Since chickens don’t sweat, they have to cool their bodies off another way. The comb filters out some of the heat so the chicken doesn’t get too hot, and it keeps the chicken warm in the winter.

Health Concerns

The look and feel and look of the comb can indicate a problem.
