History Of Sapphire Gem Chickens

If you quickly search the internet, you will likely get little details on the background of the sapphire gem chickens. 

Much is unknown about the origin and background of this beautiful breed of designer chicken.

According to most breeders and chicken keepers, the original sapphire gem chicken breed hails back to the Czech Republic.

It is an unofficial chicken breed first produced by a breeder in the Czech Republic who crossed a Barred Plymouth Rock chicken with a Blue Plymouth Rock chicken.

Some sources have also suggested that the Sapphire gem chicken was first bred by crossing a Disallowed Plymouth Rock and a Blue Plymouth Rock.

The breed is closely related to the Andalusian chicken, a heritage breed dating back to the mid-1800s.

As the names suggest, the Barred Plymouth Rock and the Plymouth Rock originated in Massachusetts. They were first bred in the 19th century. 

They carry the dominant blue gene that is selected for the plumage color. The chicken was purposefully bred for its high capacity for egg production and beautiful appearance. 

Advantages of the Sapphire Gems chickens:

  • High egg production
  • Attractive plumage
  • Pleasant personality
  • Adapts to many climates
  • Good foragers
  • Easy to care for
  • Good to raise with other breeds

The Sapphire Gem chickens do not breed true because of the nature of their genetics. This means you can breed two Sapphire Gem chickens, but they will not necessarily produce actual Sapphire Gem chicks. It would be best to introduce the two original breeds to get the desired color for the breed standard. 

Breed Standard And Appearance

As stated earlier, the Sapphire Gem is an unofficial chicken breed. They are being refined to develop the best examples of the breed.

This means some chicks may appear more solid black or blue than lavender or greyish at some point. 

The color variation does not make the chicks less Sapphire Gem chicken by egg-laying capabilities or temperament. However, it may result in a mature chicken, not of the desired color. 

Since they are so-linked breeds, you can easily identify female and male chicks by the color of the feathers once they have hatched.

Male chicks usually have a white spot on their wings or head, while female chicks tend to be blue in color. 

The Sapphire Gem chickens have an alert and upright appearance. Their feathers are ordinarily medium to dusky blues and lavender.

The chicken’s name (Sapphire Gem) comes from its plumage’s purple and blue hues. Mature male Sapphire Gem chickens are primarily blue in appearance and may have some barring.

On the other hand, hens are more solid purplish, or blue hue. In addition, the hens usually have a single comb on the top of their head.

The breed is generally medium-sized, with the roosters reaching a weight of about 6 pounds when mature. On the other hand, mature Sapphire Gem hens have an average weight of about 4 pounds. 

Personality And Temperament

Most breeders and chicken keepers describe the Sapphire Gem as a friendly and even-tempered chicken breed. They are calm birds that can perform well in nearly all environments.

You can expect these chickens to be very calm even when under stress. Some keepers say the Sapphire Gem chicks are quieter than other breeds.

The Sapphire Gems are good foragers and make great free-range birds. They are also keen observers.

This means they can be more alert to their predators’ presence than other chicken breeds.

Sapphire Gem Egg Laying

If you have been looking for a chicken breed that can lay a fair number of eggs in a year, then a Sapphire Gem hen can be a good option.

The breed was specifically bred for the production of eggs. It was originally not bred to be a good meat-producing chicken.

Under good conditions and care, a mature hen can 4 to 5 eggs in a week. This translates to about 300 eggs in a year.

The Sapphire Gem hens can be considered great egg layers compared to most chicken breeds. They start laying eggs when they are 17 to 24 weeks old. 

Some people sometimes confuse this breed with the Sapphire chicken. Therefore, you can mistakenly think that they lay blue eggs.

However, the Sapphire Gem hens normally lay brown eggs that are mostly large or extra large. They are prolific birds with year-round laying habits.

This means the hens will keep you busy collecting eggs throughout the year. Like most other chicken breeds, the Sapphire Gem hens will likely drop their egg production rate by about 20% after their first two years of laying. 

Health Issues And Care

Like their close relatives, the Plymouth Rocks, the Sapphire Gem chickens can do well as backyard chickens because of their quiet nature.

They also do not mind being confined as long as there is plenty of space for exercise and they are provided with entertainment to avoid boredom.

The breed prefers warm weather and will thrive well in very hot climates. The Sapphire Gem chicken is also known for being a hardy chicken breed and can survive in areas with cold winters.

However, you must provide indoor shelter for your bird during winter if you raise your chicken in a colder climate.

Offering your birds warm shelter will also prevent various conditions, such as frostbite, which can lead to the falling off of the comb. To prevent this from happening, you can coat their combs with Vaseline. 

The Sapphire Gems are born healthy chickens without any hereditary issues. However, you will have to treat them for any disease that could come along the way.

The birds are also susceptible to poultry parasites such as mites and lice. Therefore, you must check and treat these parasites before they infest further regularly.

You should also provide your chickens with a healthy diet to ensure they remain healthy for many years.

Any breed of chicken will require a healthy and well-balanced diet to live a healthy and more productive life. Sapphire Gem chicks should be fed on an 18% to 25% protein chick feed.

You can introduce a high-protein diet once your chicks have matured and the hens start laying eggs.

This will ensure that your birds have enough energy to be active most of the time. It will also ensure that your hens have enough nutrients and protein to lay strong-shelled eggs and remain healthy throughout their lifespan. 

Hens and those about to lay eggs should be provided with extra calcium feeds to help produce quality eggs with strong shells. The easiest way to achieve this is by giving your chickens laying poultry feed.

In addition to a balanced diet, you should provide your chickens with enough clean and fresh water. Lack of water can cause dehydration, eventually leading to your chickens’ death. 

Coop Setup and Roaming

Chickens usually require good shelter. The coop setup is one of the first things you must consider before establishing a backyard flock. Your coop should be large enough to accommodate all birds.

When designing a coop for your Sapphire Gem chickens, you should create a space of about five square feet for every chicken inside the coop.

Sapphire Gems are average-body chickens that will not take large spaces compared to other large chicken breeds such as the Jersey Giants.

Although the birds tolerate confinement, they are natural foragers that should be allowed to roam freely whenever possible.

They are also perceptive and highly sensitive to their environment. This means they can sense their possible environmental predators and avoid them.

If you do not have enough space for your birds to free-range, you will have to make the dimensions of your coop larger.

Also, you will have to ensure they are safe and secure from predators, especially if you keep them in an enclosed run. 


Sapphire Gem chickens are among the best chicken breed to add to your flock. The breed, a cross of the Blue Plymouth Rock and the Barred Plymouth Rock, is a good egg producer.

They will require good care to live a healthy and productive life.
