Different types of selective breeding in chickens include
Egg laying hens are chosen in selective breeding because they lay more eggs at a faster rate than the average chicken. Because of this breeders want the hens to pass off these genes to their daughters. These types of hens get brittle bones because much of her calcium is uses for making the egg shells. Broiler chickens are used for selective breeding because they inherit the gene of having more meat on their body. Since this happens, many of these chickens have lame legs. These chickens eat day and night, which causes them to grow at an abnormal rate.
What are Desired traits with these breeds?
The desired trait for the egg laying hens are laying eggs at a fast rate
The desired trait for a boiler chicken is a large amount of muscle (meet for eating.)
How are chickens selectively breed?
To selectively breed a chicken a breeder will first find a chickens with the desired traits. These chickens mate and create a offspring that most likely inherited these same traits. This cycle is continued. Selective breeding is done on farms, in houses, and in factories.
- Egg laying hens. Egg laying hens are hens that are breaded to lay a lot of eggs (they still grow at a normal rate.)
- Broiler chickens. Broiler chickens are chickens that are breed for meet and grow twice as quickly.
