DOMINANT BLUE D 107 is one of our most popular programs thanks to its originality in the blue feather colouring and the option of using colour sexing in one-day-old chickens. It is used as a final hybrid for self-sufficient farms in the Czech Republic and in many other countries. Capons are used to produce traditional, highly delicious poultry meat.
Owing to its attractive colouring, it is also used in exporting parent breeding pairs to many countries where it is primarily used in self-sufficient family farms for the production of table eggs.
The asset is the high productivity, namely laying from over 290 to 300 eggs, verified in cage-intensive farming conditions at a testing station. Light brown eggshell colour is characteristic.
Attractive is the grey to blue feather colour of adult laying hens with barred cockerels.
This program is the result of cross breeding original dominant homozygous BlBI genotype of the Plymouth Blue Rock (BLPR) paternal population and the Barred Plymouth Rock (BPR) maternal population. Colour sexing is applied when hatching one-day-old chickens using the "B" allele of the Barred gene, where one-day-old cockerel acquires the dominant allele of this gene from the mother and is barred with a white dot on its head and one-day-old hen acquires the recessive "b" allele from the father, which does not cause barred marking, and consequently the hen is dark without white marking on her head.
