Chicken sexing is the method of distinguishing the sex of chicken hatchlings, usually by a trained person called a chicken sexer. Chicken sexing is practised mostly by large commercial hatcheries, who have two different feeding programmes, one for the females (or hens) who are destined to lay eggs for commercial sale, and the others for the males (or roosters), most of whom will be fattened up for sale as meat. The chicken sexer puts the chicken hatchlings on the appropriate track early, enabling those chickens to receive optimal nourishment for their likely commercial role from an early age.

Different segments of the poultry industry sex chickens for various reasons. In factory farms that produce eggs, males are unwanted; for meat production, separate male and female lines for breeding are maintained to produce the hybrid birds that are sold for the table, and chicks of the wrong sex in either line are unwanted. Chicks of an unwanted sex are culled (i.e., killed) almost immediately, to reduce costs.

Methods of chicken sexing
There are two chief methods of sexing chicks:
feather sexing
and
vent sexing.


Feather sexing

Feather sexing is easy, but it requires that the chickens be specially bred to manifest their sex in differences in the feathers as hatchlings. Male chickens in these breeds have longer wing pinfeathers than the females do, which makes them relatively easy to tell apart. Most chickens do not have these traits bred into them, and the hatchlings are identical to all but the skilled eye of the professional chicken sexer.


Vent sexing

Vent sexing involves literally squeezing the feces out of the chick, which opens up the rectum slightly, allowing the chicken sexer to see if the chick has a small "bump", which would indicate that the chick is a male. Some females have very small bumps, but rarely do they have the large bumps male chicks possess.

Vent sexing is not easy. The sexual organs of birds are located within the body; the professional vent sexer has studied their external appearance, which can fall into as many as fifteen basic patterns, and learned to identify which ones are male and which female. Vent sexing is a difficult trade to master; many professional vent sexers are Japanese, where the art originated. The mystery of vent sexing was revealed to the Western world when a seminal paper was published in Japan in 1933 by Professors Masui and Hashimoto, which was soon translated into English under the title Sexing baby chicks. After Masui and Hashimoto's discovery, interested poultry breeders brought in people who had been trained by them to teach the art, or sent representatives to Japan to learn it. The skill is complex and has been likened to skill at playing chess and other crafts or games where pattern recognition is the key to success.


The chicken sexing machine

In the 1950s, several machines were invented that illuminated and magnified the cloacas of newborn chicks, and chicks could be sexed by inspecting them with this machine. This method is obsolete; only two manufacturers made the machines, and both have left the business

once you have chicks interior the nest you're meant to look interior the container as quickly as interior the morning and as quickly as at night, till the chick is approximately 2 weeks previous then you truly look interior as quickly as an afternoon. you may verify in the event that they're being fed with the help of observing their crop (the bubble around the chest and the back and front of the neck) it relatively is going to be crammed with a crop milk and then because it gets older it relatively is going to be crammed with what ever you feed the father and mom. whilst it cries it in basic terms skill it relatively is hungry. yet another selection in case you dont decide for to look interior the nest then you truly can placed a digital camera interior the nest ( a very small one) and attatch it to a larger exhibit screen after which you would be able to locate interior 24/7 without worrying the nest/father and mom and little one.

No way to tell for certain, but the girl chicks are probably the ones talking all the time, and the guy chicks are the ones with really bad memories.

I think male chicks have a different colored feather on their tush. You have to be looking for it to find it though.

the males have a deeper "cheep"
The females chase the males and cheep "what about me? I need to talk about our relationship. I know I was just born but I am not getting any younger"

You are welcome

You don't always know. Many times you have to take them to a vet to get a DNA test.

Uh...I'm pretty sure you can't know while it's still a chick. But I could be wrong.

you don't, you have to get a DNA test to know that
