The Sapphire Gem is a sex-linked hybrid created by a breeder in the Czech Republic. It is a hybrid that contains the Dominate Blue gene and is known for being a good layer of large brown eggs. They do best in warmer climates and are close to the Old Andalusians.

The Dominate Blue gene:
This gene is the, "Result of crossing synthetic original paternal stock Blue Plymouth Rock with Barred Plymouth Rock maternal stock," (http://dominant-cz.cz) the resulted chick is sex-linked and can be identified by males having a white head spot and barring, while females have absence of a head spot, no barring, and are darker.

Pros: Big as day-olds, fairly calm (even as youngsters), fast-growing
Cons: None
I bought these pullets in the coldest time of the year so I could get more eggs as soon as possible. Glad these birds are big (as babies) and hardy! They were virtually feathered at 4.5 weeks. At 5 weeks, I started to see the occasional feather dropped, as if they were already starting to molt into their adult plumage! The babies were noticeably bigger than the Amberlinks I bought in the same hatch date, so I'm expecting some big eggs. They seem to be growing quickly also, as of 6.5 weeks.

Pros: Beautiful birds, friendly personality.
I have two Sapphire Gem pullets, they have been wonderful so far. As baby chicks, they enjoy attention, and jump up onto my hand/knee to be pet and held.

I love the look of these chickens - they have such a pretty grey (blue) - with blue legs. Single comb.

I have yet to get eggs...so I'll be looking forward to my "big brown eggs" - I may come back and update this soon, once my gals start laying regularly :)

Do they breed true? In other words, when you breed a male and female together, are the chicks sex-links too? OR do you have to mix two colors, or breeds to continue with the sex-link chicks?

They don't breed true in color.
But, even the original show strains of blue plymouth rocks don't breed true in color.
They give 50% blue, 25% splash and 25% black.
Also, the original blue plymouth rock must have bright yellow legs.

Look at the official site of the dominant blue d 107, to understand more.

Dominant CZ is a trustworthy company and they sell f1 crosses of plymouth rocks. They sell columbian, blue sex linked and black sex linked. O N L Y the columbian breeds true in color. The others are created from different colors of the same breed in order to be color sex linked at hatch.

They are a bit smaller in comparison to the heritage ones.
But smaller size means smaller appetite and less feed consumed.
They are also bred for an optimum and an excellent egg production, even through winters and for a very good egg size and long circles of laying.
Give them the right feed and they will be your best layers.

The blue SL lays pinkish/reddish brown eggs. The black SL lays commercial brown eggs. The Columbian lays light creamy tinted brown eggs.

Sometimes their eggs are speckled.
 
I reluctantly acquired a pair of Sapphire Blue pullets (always shop by yourself at a feed store), and the 5-week-old girls are lovely. Like my previous brooded babies, Vanna and Petra scream bloody murder when I life them out of the brooder. Unlike my others, they both then delight in perching on my hands and arms like the parakeets my family had when I was a child. They are beautiful and I am hoping they thrive during the cold Iowa winter.

They won't have any provlem. They are plymouth rocks. So, they are hardy.
