The Chocolate Orpington is a very new addition to the range of colours available and has only become established from around 2010.
It was first created in bantam and then the journey from bantam to large fowl was a slow process as the Chocolate gene is sex-linked dominant and the bantam gene is sex-linked as well.
The Chocolate Gene
Chocolate is a sex linked recessive gene.
So a cockerel needs two copies of the gene to be chocolate but the hen only needs one.
Chocolate x Chocolate = 100% Chocolate
Black split Chocolate cockeral x Black hen = 25% Black split cockerals/ 25% Black cockerals/ 25% Black hens/ 25% Chocolate hens
Chocolate cockeral x Black hen = 50% Black split cockerals / 50% Chocolate hens
Black cockeral x Chocolate hen = 50% Black split cockerals/ 50% Black hens
Black split Chocolate cockeral x Chocolate hen =25% Black split Chocolate cockerals/ 25% Chocolate cockerals/ 25% Black hens/ 25% Chocolate hens
