22. GRADING AT FARM
At farm separate low weight birds and feed them
separately and provide a bit large amount of ration
then the heavy weight chicks.
The feed of heavy weight chicks is maintained so as
to get a uniform body weight among all the chicks.

24. ADVANTAGES OF CHICK GRADING
Achievement of purpose of providing quality chicks
to the customers.
There is good reputation of the hatchery
Uniformity among the flock is maintained.
Removal of birds which will not show better
performance in the future.
Better profit is obtained.

25. Sexing Of Chicks
Several methods are used to determine the sex of a
day-old chicks. Some are effective only with certain
breeds or crosses, while others are universal. The two
chief methods of sexing chicks are
 feather sexing
vent sexing.
25

26. Vent sexing
Vent sexing, also known simply as venting
Involves squeezing the feces out of the chick, which
opens up the chick's anal vent (called a cloaca)
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 also have bumps, though they are
rarely as large as those of male chicks
26

27. Feather sexing
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.
Female chicks have primary wing feathers that are
significantly longer than the coverts.
The male chicks have primary wing feathers that are
shorter, about the same length as the coverts.
27

28. PACKING OF CHICKS
The chicks are packed in chick boxes of standard size.
They are soft at the time of packing so leave them for
4-5 hours to become hard.
Attach label of sex, breed, date of hatch, and grade of
chicks on the chick box.
28

29. RECORD THE DATA
The following data should be recorded.
Breed
Number of eggs set
Number of quality chicks hatched
% age of total hatchability
Number of “grade outs”
% age of “grade outs”
% age of extra chicks given to customer.
