The instinct of the Chicken - Animals instincts
Table of Contents
The hen can distinguish a rotten egg between the eggs on which it is lying, and discards it and throws it away, and it can distinguish an unfertilized egg from a fertilized egg. And she is constantly inspired by turning the eggs that lie for every known number of hours.. And if it wasn't for this stirring, the embryos would have died because of their attachment to the shell. And the newborn chick knows where the weakest place is in the egg to peck it with its beak and come out.
How the chicken reproduces?
The chicken reproduces by sexual mating between it and the rooster to
produce eggs, and the young hen is called a chick while the scientific
name of the chicken is (Gallus gallus). the fertilization of eggs
représentas the first stage of the life cycle of the chicken, at this
stage the rooster tries Mating with the hen, where the hen chooses the
appropriate rooster, and takes as a consideration when choosing the
following:
- The appearance of the rooster, which gives her a good impression of his health.
- The ability of the rooster to find food .
- The possibility of turning into a leader of the herd .
The mating process is short as it takes less than a minute Once both
the hen and the rooster mate, fertilization takes place in the funnel,
which is the part of the reproductive system that follows the ovary,
and the egg remains in this area for about 15 minutes only.
Laying eggs
The ovary of a laying hen contains thousands of small eggs or the
yolk of the future egg, and when the yolk is ready, it moves from the
ovary to the oviduct, then moves through an area of the oviduct called
the magnum, into which the egg white protein is added, and then moves
quickly through Part called the isthmus, where the cortex membrane
fibers are produced. The egg enters the gland of the shell, and the
shell is formed within a period of about 20 hours, and this process is
called calcification, then layers of calcium carbonate are added to
form the shell, and during the last two hours of shell formation, the
shell pigment (white or brown) is produced, and it appears on the
outer layers for the crust.
Most chickens lay their first egg at about 18 weeks of age, and then
lay an egg almost daily after that. In their first year, they can lay
up to 250 eggs, after which the number of eggs will naturally decrease
every year. Unable to lay eggs. Egg care is the first thing you need
in the process of hatching chicks, fertilized eggs.
Fertilized eggs
can be collected from hens mated with roosters, and as we mentioned
previously, unfertilized table eggs; Therefore, it will not grow into a
chick if it is placed in an incubator. Fertilized eggs can be obtained
from the hatchery, or from poultry farmers with roosters in their
flocks. Before incubation, the fertilized egg can be stored for a
maximum of 7 days, and kept at a constant temperature of 12-15° Once
fertilized eggs are placed in a warm incubator, they may develop over a
period of time 21 days to produce chicks, with proper preparation and
care of the incubator. The egg incubator is a closed structure, with a
fan and a heater; To keep the eggs warm during the incubation period of
21 days, the temperature and humidity inside the incubator are critical
factors for successful hatching of eggs, and the temperature range is:
37-38. 5 times a day, making sure to wash hands or wear clean gloves
before touching eggs; To prevent the transfer of skin oils or germs to
the growing chick inside the egg.
The chicks come out
The egg hatches and the chicks come out wet, and they are tired and
their legs are shaking.
Some chicks come out very quickly within an hour or less, while some
chicks sometimes take more than 24 hours, and they should be left in
the incubator until they are completely dry.
Care of chicks
Once the chick is out and dry it can be safely moved to the nursery
area, and once inside Chicks to the nursery, they must be provided
with water and nutrition Put it under a light board or incubator, and
the food should contain enough protein, vitamins and minerals, to grow
for the next several weeks. The first weeks of the chick's life
witness an amazigh rate of growth and development, knowing that some
breeds grow faster than others. From them by the fourth week, and at
about 7-12 weeks, males and females will be distinguished, and then
puberty begins.
