The sex-linked slow-feathering gene can be used for crosses where the sex of the chicks can be determined at hatching time by the length of the wing feathers. A cross between a fast-feathering male and a slow-feathering female results in offspring where the female chicks have primary wing feathers that are significantly longer than the coverts ...
Figure 1. Feathering types in ten-day-old chicks.Left: Fast normal-feathering chick. Right: Delayed-feathering chick carrying sex-linked K gene. Delayed-feathering in chickens is a genetically determined delay in the first weeks of feather growing, which occurs normally among the chicks of many chicken breeds and no longer manifests itself once the chicken completes adult plumage.
Chick. In poultry farming, in-ovo sexing is a chick sexing method carried out while chicks are still in ovo (Latin for "inside the egg"). There are various methods to determine a chick's sex in the 21-day incubation period before it hatches. In-ovo sexing technology has branched into two categories, invasive and non-invasive.
The B1 allele is causing the typical sex-linked barring phenotype/ appearance and is present in most modern sex-linked barred chicken breeds. Females or male chickens carrying the B2 allele in the heterozygous condition show a defined barring pattern but in the homozygous condition, males are essentially white with very little pigmentation.

The long feathers of the neck Primary flights or primaries: The longest and outermost feathers of the wing Saddle feathers Feathers covering the back or saddle before the tail coverts; in cocks they are long and pointed divided into upper and lower saddles Scapulars Short feathers on the upper side of the wing near the body Secondaries
Males of most chicken breeds distinguish from their females in having longer, sharp and more scalloped feathers in neck, hackle, saddle and wing bows. But in some breeds, like the fancy breeds Sebright and Campine and some game breeds like Pettai Madhirione can see males that have a plumage completely similar in all aspects to that of females.
