There are many complaints from farmers to egg sellers about the lack of production, especially regarding eggs not being produced at the expected level.
The egg is not fertilized, if the hen lays an egg without being inseminated by a rooster, it is 100% certain that the egg will not be fertilized.
Place the roosters in this recommended ratio of 8-10 hens to one rooster and make sure the rooster insemines the hen.
Hair line cracks (cracks invisible to the naked eye in the egg)
Chickens usually lay eggs with hard shells, so if the eggs collide too much while the hens are laying, they may not crack but will develop internal cracks that you will only see if you are experienced at sorting eggs or by shining a flashlight in the dark.
Causes of these invisible cracks
Having a small number of nests in proportion to the number of chickens; it is recommended that one nest accommodate 4-5 chickens.
Do not put straw or rice bran in the nest when the hen lays eggs, otherwise the egg will hit the floor, metal or wood and cause cracks.
Solution: Place rice bran or rice husks in the chicken coop and change them every two weeks.
Delaying egg collection and having more than 4 eggs in one nest creates an opening for the eggs to collide and cause internal cracks.
Solution I advise anyone, whether a large or small farmer, to set a schedule for collecting eggs, for example
Round 1: 1:30 AM,
Round 2: 3:30 AM
Round 3: 4:30 AM
Round 4: 5:45 PM then go eat
Round 5: 8:00 PM
Round 6: 10:30 PM
Then you will no longer hear the cracks or they will be reduced by a large percentage in the field.
When transporting eggs,
make sure the eggs are arranged on a tray and placed in a sturdy box to prevent looseness that could cause the eggs to collide.
The problem with machines not producing milk, here pay close attention to
Temperature and
Humidity

Pay attention to the machine you are using, refer to the manual guide.
Eggs take a long time to mature from the day they are laid until they are placed in the machine.
Professionally, eggs placed in the machine are advised to stay in a special cold room *(Cold room with a temperature of 16-20°c for a period not exceeding 7 days and then placed in the machine)
However, since many farmers do not have this special room to store eggs at the right temperature, it has been advised that eggs should not be kept in the machine for more than 4 days, for one main reason.
Fertilized eggs (containing seeds) when exposed to heat begin to develop into chicks. If the egg remains in the incubator for a long time before being placed in the machine, if you put it in a high temperature incubator, it happens that the chick that has begun to develop will die early *(early death)*. Pay close attention to this.
Eggs are turned when placed in the machine (this does not prevent hatching but causes many chick deaths before hatching)
Note:
Make sure the sharp end is facing down and the blunt end is facing up (air sac is at the top) to help the chick get air into the egg.
NB: Breeders, ensure that you place clean eggs in the machine to avoid the accumulation of bacteria that can lead to infection in the chicks you sell.
After hatching, make sure you clean your environment thoroughly with strong disinfectants to kill a large percentage of parasites
