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.Our SGs in the US are not coming from dominant CZ.
At this time our hatcheries are maintaining their own flocks so what applies there doesn't necessarily apply here.
They aren't using rhodebars but maybe a similar type hybrid.
And the mother hens are barred rocks and rhodebars. But, the rhodebars of dominant CZ are selected for small size and feed conversion, not for the official standards. They may also cross their rhodebars to the rhode island reds. In both the crosses, the males are splash Plymouth rocks.
I trust hy-line, cobb, dominant cz and tetra for many years. I can "feel" their strains. I have raised millions of their blue sex links. Only dominant cz offer these strains worldwide.
Dominant CZ also offers strains of leghorns. White, brown, mille fleur and light Columbian. I sold 80 brown leghorns of their strain the last year. I had them for 4 years and they were laying and laying and laying enormous chalky eggs.
I want you to giveme some advice on breeding the german italiener strain of leghornsfor utility purposes. I want to create my own parental stock, bred for the outdoors and for balanced traits, not only for layer feed conversion.
