You will ask someone expert. You can also check the chicken genetics calculator. Bear in mind that some of the sapphire gems have a barred rock as a mother while others have a rhodebar as a mother. You can't know. And I repeat, they are hybrid layers for keeping, they are not for breeding. If...

You have a passion for poultry and you care about your girls. This means you are a great keeper and breeder. Sapphire gems are actually blue sex linked hybrids of dominant CZ. They are heavier than other commercial hybrids. This means that they are adaptable to poor feeding systems and farm...

I repeat. They are not designed for reproduction. They have the bigger needs of the hybrid layers, like the legendary hy-line layers, but have less stress burn out later and utilize pasture much better than the layers of other companies. If bummed, you need to provide oyster shell.

I am 100% sure that they use the strain of the dominant cz!!! The company has agents in the States. Most of the sex links, leghorns, easter eggers and olive eggers sold in the US are officially bred from lines of dominant CZ. And the mother hens are barred rocks and rhodebars. But, the...

17% layer feed is OK. Extra protein will cause egg binding problems.

The gold leakage is from the cross between rhodebar females and splash rock males, a cross created from dominant CZ breeders. The mother company is from Cz Republic. Here is the link: https://dominant-cz.cz/programy/hneda-skorapka/dominant-modry-d187/

Dominant Blue D 107 hybrids are bigger than the ISA browns and handle much better their hard working ability by overlaying eggs. Don't make the protein higher. Just don't take their eggs for three to five days so to stop laying for a bit and take a rest. Just this.

They are not a rare breed, but a laying hybrid.

Oh my God, sapphire gem is a hybrid. It is actually dominant blue d 107. It is a heavy version of a hy-line brown type hybrid. But, blue SL and not red SL. It produces better than other hybrids in poor feeding and low density rations and it utilizes much better the free range. Understand it. I...

Help me with my utility black leghorns breeding purposes.

The mother company is dominant CZ. Gold leakeage is because of splash color. Splash color can hide everything. I have created a thread about utility black leghorns. I need your help.

Dear, they are a commercial hybrid, a product based on layer strains of plymouth rocks in a blue sex linked way. They lay pinkish brown eggs of a large, extra large and jumbo size, they forage better than other hybrids and they burn out later than other commercial hybrids. They do not breed true...

Cockerels have white spot on their heads when hatch. They become blue barred later, not solid blue.

Those terracotta pinkish brown eggs are so lovely. Mine lay about 90g weight eggs.

What is barn gems?

Sorry, but you simply gain nothing when you breed from sapphire gems. They lack the balance that paternal qualities express. They are designed only for laying, winter laying, minimum feed consumption and being slaughtered to produce meat. They are production hybrids, bot a breed.

Depends on weather conditions. They need light to lay young.

Which of them is layed by the sapphire gem hybrid?
