This is how baby chicks are breathe
This video shows that how baby chicks are breathe in Hatchery. It is a place for artificial breeding where eggs are hatched under artificial conditions. In commercial chicken farming it is the first step or the second step if you think the egg came first. Chicks come from eggs fertilized by madding but a hand Conley eggs without madding. Those unfertilized eggs are the ones we eat. The fertilized ones go to the Hatchery three or four days after being laid. Hatchery workers transfer the eggs onto special trolleys then roll them into the incubator where the temperature and the humidity level mimic natural conditions.

The egg yolk, egg white and shell all nourish the embroil. Every hour the tray shifts 45 degrees to the opposite side and back simulating how hens turn their eggs while waiting for them to hatch. After 18 and a half days the eggs come out of the incubation and go onto a conveyor belt, they pass under an infrared sensor that detects any whose colour is too transparent. These are unfertilized eggs that slip through. The sensor triggers a suction device to remove them, they go to a rendering plant to become animal feed. The fertilized eggs continue along to the next station to be vaccinated against Merrick disease. Automated needles pears a hole in each shell and inject the vaccine into the amniotic fluid surrounding the chick. Now a suction device transfers the eggs to hatching trays (168 eggs/tray). About 150 of them can be expected to hatch, the rest died in incubation or have physical defects. On the 19th day the chicks use their beaks to crack a hole through the shell then a horizontal line all around. After 6-8 hours the chicks finally emerge from the shell. They are covered in short feathers called down and they are able to walk and see. After about 4 hours their down has dried. Now the workers roll the chicks towards called the separator, a machine that separates the birds from the shell halves. The shells are larger than the chicks so they stay on top while the chicks fall down to a conveyor belt below. The shells which are high in calcium go to a rendering plant. The chicks move on to be classified according to gender. Workers put the females down one shoot, the males down another.

They determine the sex by checking two rows of the feathers. If one row is shorter than the other, the chick is female and if the rows are of same height then its a male. An optical counter tracks the no of males and females. The chicks now fall into specially design transportation boxes (102 chicks/box). Some clients request that their ordered chicks be vaccinated against bronchitis, those boxes pass under an aerosol sprayer that sprinkles them with a mils dose of vaccine. Poultry farms raise chicks for either meat or eggs. Female used for egg production begin laying eggs at about 20 weeks of age. For meat production female reach smarter weight in about 38 days, males depending on market size take from 40-65 days.
