Introduction to Hy-Line brown-shell laying hens

HY-LINE VARIETYBROWN is a four-line excellent supporting breed bred by Hy-LINE INTERNATIONAL in the United States. Laying hen breeds. Our country introduced it in the 1980s. Currently, there are many ancestral or parent breeder chicken farms across the country, and it is one of the most commonly raised breeds of brown-shell laying hens. Hy-Line Brown, like other brown-shell egg commercial matching chicken breeds, is also a four-line matching chicken breed. The male parent is the Luodao red chicken variety, while the female parent is the Luodao white chicken strain. Since the male parent Luodao Red and the female parent Luodao White carry sex-linked gold and silver genes respectively, the commercial generation produced by their matching crosses can identify the male and female based on the color of the fluff. The male parent of Hy-Line brown chickens, Luodao Hong, has the appearance characteristics of a typical dual-purpose chicken breed and a medium-sized laying hen. The Los Angeles Red Chicken is native to the United States and was bred in the early 20th century. It has two varieties: single comb (both Hylan Brown male parents have single comb) and rose comb. The ear leaves are red, the body feathers are dark red, and the tail feathers are black and shiny. The skin, beak and shanks are all yellow in color. The chicken has a medium body and a long and flat back. The female parent, Luodao Bai, has a red single crown, red ear leaves, white body feathers, and yellow skin, beak and shins. The body is medium-sized, and the back is not as long and flat as Luodao Hong. Hylan brown commercial generation chicks are first born, the female chick is red all over, the male chick is all white, and they can distinguish between male and female. However, because the female parent is a synthetic line, a few of the red-fluff female chicks in the commercial generation have dark brown stripes on their backs, and some of the white-fluff male chicks have light brown stripes on their backs. When commercial hens reach adulthood, their feathers are basically (overall) red, with a little white on the upper end of their tails. The chicken has a compact head, a single comb, and red ear leaves, sometimes with some white. Skin, bill and shanks yellow. The body is strong and basically ingot-shaped.

Create conditions for high and stable production.

How many days does it take for Hy-Line brown laying hens to start laying?

The age of Hy-Line brown laying hens to start laying should be controlled at 140 days, that is, eggs will appear in 140 days. The egg age of brown-shell laying hens is about 15 days later than that of white-shell laying hens. They start laying too early. The eggs produced by the laying hens are small and the peak period lasts for a short time, thus reducing the periodic egg production of the laying hens. Only appropriate The economic benefits can be obtained by controlling the laying time of laying hens so that the eggs produced by laying hens are large and the peak egg production period lasts for a long time.
