Sapphire Gem Chicken: Eggs, Temperament, Size and More

For those looking for a novelty chicken breed that holds its own in terms of egg production, the Sapphire Gem chicken is the breed for you.

Sapphire Gem Chicken guide

This fantastic specimen, while not an official breed recognized by the American Poultry Association, is an attractive, showy sex-linked hybrid bird with colorful plumage that was derived from crossing two heritage and hybrid breeds.

But don’t you worry, we’ll talk about all of that; after all, we’re here for the Sapphire Gem chickens. Let’s start from the beginning, the origin of the literal gem that is Sapphire Gem chicken.

History of Sapphire Gem Chickens

Not a lot is known about the origin of this fancy new breed of designer chicken. A quick Internet search will reveal little detail on the background of this bird. There is even a fair amount of debate amongst breeders and farmers on what constitutes a true ‘Sapphire Gem.’

We do know that the original Sapphire Gem chicken hails back to the Czech Republic. This unofficial breed was first produced by a breeder in that country who crossed a Blue Plymouth rock chicken with the Barred Plymouth rock.

Some suggest, however, that these birds may also be bred by crossing different variants of Plymouth Rock chickens.

The Sapphire Gem chicken is closely related to the Andalusian chicken, a heritage breed that dates back to the mid-1800s. The Plymouth Rock and Barred Plymouth Rock breeds, as their names suggest, originated in Massachusetts and were probably also first bred in the 19th Century.

The Sapphire Gem breed carries the dominant blue gene, which is selected for the color of the plumage. This hybrid chicken was purposefully bred both for its beautiful appearance and its high capacity for egg production.

Advantages of the Sapphire Gem chicken breed:

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

Because of the nature of their genetics, the Sapphire Gem does not breed true. In other words, you may breed two Sapphire Gems, but they will not necessarily produce true Sapphire Gem chicks. It is often necessary to continue introducing the original two breeds in order to produce the desired look for the breed standard.

Breed Standard and Appearance

As an unofficial breed, the stock is constantly being refined to produce the best examples of the Sapphire Gems. This means that sometimes there may be some chicks that appear more solid blue or black than grayish or lavender.

These variations in color do not make the chicks any less of a Sapphire Gem by temperament or egg-laying capabilities but may produce a mature bird that is not of the exact coloring desired.

Because the Sapphire Gem is a sex-linked breed, it usually is an easy task to identify male and female chicks. And that is by the color of their feathers (shortly after they hatch). In similarity to a black sex link breed, female Sapphire Gem chicks tend to be a solid blue color, while male chicks tend to show a white spot on their heads or on the wings.

Sapphire Gems have an alert, upright appearance. The feathers of this breed come in a range of medium to dusky blues and lavender. The blue and purple hues of the bird’s plumage are what give it the namesake ‘Sapphire Gem.’

Adult males are largely blue in appearance but often have some barring. Barred plumage, according to R. C. Punnett and M. S. Pease, authors of the paper “Genetic Studies in Poultry,” refers to feathers on which “bands of different color are arranged alternately along the feather at right angles to its main axis.”

Adult females are more of a solid blue or purplish hue. The hens have single combs on the tops of their heads.

The Sapphire Gem is a medium-sized breed of chicken. Roosters will generally reach a weight of around five pounds at maturity. A fully mature Sapphire Gem hen will usually weigh around four pounds.

Personality and Temperament

Many describe the Sapphire Gem as an even-tempered or friendly chicken. In an interview with Paws 4 Hearts Rescue, an employee of Hoover’s Hatcheries states that certain personality traits were encouraged as part of the breeding process with the aim of producing “a calm bird that performs well in all environments.”

Hoover’s Hatcheries also suggests that the Sapphire Gem breed should get along well with most other chickens.

Some chicken farmers have even reported that the chicks tend to be quieter than the young of other chicken breeds.

Because they seem to be good foragers, the Sapphire Gem makes a great free-range chicken. They also seem to be fairly keen observers, which means they may be more alert to the presence of predators than some other chicken breeds.

Sapphire Gem Chicken Egg Laying

If you seek a chicken that will produce a fair number of eggs, the Sapphire Gem hen is your go-to. These birds were specifically bred to be good layers and are not really meant to be meat-producing livestock.

A healthy, fully mature Sapphire Gem hen will often lay close to 200 to 260 eggs in a year, or four to five eggs a week. They will begin to produce eggs between 18 and 24 weeks old.

Because this breed is often confused with another breed called “Sapphire” which produces blue eggs, some mistakenly think the Sapphire Gem also produces blue eggs. However, unlike the small white Sapphire chicken, the Sapphire Gem hen produces brown eggs.

With year-round laying habits, this prolific bird will keep you busy collecting eggs in every season. Eggs produced by the Sapphire Gem hen are large or extra large in size.

As with the average chicken breed, the Sapphire Gem hen will tend to drop in egg production by around 20% after the first two years of laying.

Health Issues and Care

The Sapphire Gem, as with its close relative, the Plymouth Rock, should do well as a backyard chicken due to its quiet nature. This site also states that they will likely not mind confined enclosures as long as there is adequate room for exercise and they are provided with some form of entertainment to prevent boredom.

The Sapphire Gem chicken is said to prefer warm weather and to thrive best in very hot climates, but this specialty breed is also known to be hardy and can also survive in areas with very cold winters. If you live in a colder climate, you should provide indoor shelter for your Sapphire Gems during the winter months.

Providing warm shelter for your birds will prevent particular conditions, such as frostbite, which can sometimes cause combs to fall off. Combs can be coated with Vaseline to help prevent this from happening.

Tips for Raising Sapphire Gem Chickens

While the Sapphire Gem is said to do well in hot climates, it should go without saying that if you intend to raise any breed of chicken in a hot climate, you will need to provide plenty of shade and cool water for your birds.

You may also find it helpful to use electric fans to provide a gentle breeze, whether inside or in a backyard enclosure. Star Milling Company, a producer of quality animal feed, also suggests providing ice, in any format, for your chickens.

The birds can stand next to blocks of ice to keep cool, or they may choose to drink the ice-cold water as it liquefies. Star Mill also suggests leaving frozen pieces of fruit for your chickens as it will encourage them to stay hydrated.

If you live in an area with cold winters, do provide indoor shelter. Keep plenty of warm, clean nesting material for your hens, and you may even consider using heat lamps or small coop heaters during particularly cold bouts.

To keep your Sapphire Gem chickens entertained, you can provide a number of amusements. You can use a rolling treat dispenser or a suet block as a way of keeping hens busy and happy, especially during the cold winter months. They also suggest adding ladders, perches, and mirrors to the coop for entertainment.

As you can see, the Sapphire Gem is a truly exceptional breed. With her stunning blue and purple plumage and her high egg production ratios, this bird is an ideal addition to your flock.

Sapphire Gem Chickens: FAQs

And finally, the internet’s most asked questions regarding the Sapphire Gem chicken breed.

1. What Color Egg Does a Sapphire Gem Chicken Lay?

The Sapphire Gem chicken breed lays brown-colored eggs. But the real question is, why is the egg color of a Sapphire Gem chicken a hot-button issue? And I’ll tell you why.

You see, the Sapphire Gem chicken breed is often confused with the Sapphire breed of chicken. The Sapphire breed of hens lay blue-colored eggs while the Sapphire Gem drops brown yolk bombs. So, remember this; Sapphire lay blue eggs, and Sapphire Gems lay brown eggs.

That’s it, confusion over.

2. How Many Years Do Sapphire Gems Lay?

We aren’t quite out of the woods with Sapphire Gems’ laying antics. Sapphire Gems start laying their brown eggs between the ages of 18 and 24 weeks. They continue laying the brown eggs at a rate of 4-5 per week and reach their peak egg production around two years old.

That’s their peak laying performance; after that, the egg numbers start to taper off. You may get the occasional egg but nowhere close to the five-per-week record.

3. Are Sapphire Gems Good Meat Chickens?

While it’s perfectly safe to consume Sapphire Gems, they are not widely used for meat. Their superpowers lie in how well and how much they pop out those brown eggs; five a week is an impressive number.


As a relatively recent breed, availability of Sapphire Gems may vary. Remember to check with breeders and sellers to ensure that you are getting a true Sapphire Gem: either a cross between the Plymouth Rock chicken and the Barred Plymouth Rock or the offspring of two Sapphire Gems where the plumage has matched breed standard.

  1. I have 4 saphire splash hens. They are 5 most old and have just started laying. I was shocked to see the first little egg. It is lt purple. When I wash it it turns dark brown. If you put it in the refrigerator and take it out it will turn dark brown again. I think the moisture makes it turn brown. When you dry the egg it turns back to light purple. I have had blue eggs and different shades of brown but this is my first light purple. Amazing. These chickens are red and white. Beautiful color.

  2. My sapphire gem is almost four months old and my favorite little girl. She is absolutely beautiful. She has a little brown on her face, dark grey neck and head and beautiful grey body. She so calm too!

    • We just got eighteen from Tractor Supply Company. We only lost two of the 18 (both within the first 48 hours) so they’re pretty healthy. We’ve had them about a month now.

  3. Your picture under the title ‘Sapphire gem chicken egg laying’ is not a Sapphire Gem. That is a blue Wyandotte. Look at the comb. That is a rose comb. SG’s have single combs.

  4. I have had 2 Sapphire Gems. They were beautiful and gentle. Both of mine laid oblong eggs-looked skinny and long. More of a medium egg size. Egg color was a light tan.

  5. I bought 10 Sapphire Gems from Tractor Supply at the beginning of August. I lost one during shipping but the remaining 9 have done great. They are the first chickens I’ve ever had and I love them. They’re so sweet and the LOVE to see me coming….always happily greeting me each time I enter their enclosure (might also have to do with the fact I bring them treats and food). LOL. They are just about 2 months old so not fully grown nor have they produced any eggs. They are very lovely. I highly recommend.

  6. I have 3 sapphire gems and 3 buff orpingtons. The gems are more frisky. They are 24 weeks old now and laying eggs. One is giving me double yolk eggs consistently for now. One is having issues not forming shells properly. They are excitable and fun to be around. I haven’t tried that hard to keep them hand-friendly, but hey are gentle and accept me moving them around as needed.

  7. Sapphire Gem Chicken are a beautiful breed of chicken that come in a variety of colors and patterns. They are a very healthy breed and are known for their large eggs. They are also very easy to care for and are a great choice
