1 Advantages of cutting the crown Avicorn breeder is a large crown type chicken. After cock is sexually mature, the cockscomb is larger, sometimes it will fall to one side, affecting the sight of the rooster, and is not conducive to eating, drinking and mating behavior of the rooster. Moreover, the cut crown can also effectively distinguish the "female hens" left by the male and female because of the discriminating mistakes, so that the rational elimination can be carried out. Cutting the crown can also reduce the damage of the rooster caused by fighting each other during the growing period and the laying period, and can also prevent the occurrence of chickenpox due to inaccurate thorns and summer mosquito bites. In the cold winter in the north, it is also possible to prevent chicken crown frostbite caused by poor insulation due to the cold weather.
2 Operation method of cutting the crown There are two methods for cutting the crown of the rooster: The first method is commonly used. After the male and female are identified during hatching, the selected species of male chicks are cut and the scissors are used to cut the crown. The second method is to pick a red rooster, developed pectoral muscles, prominent keel, good body condition as a breeding rooster, and cut the crown at the age of 35 to 45 days. At this time, it is mainly used for cutting or red burning. The pliers cut the crown.
3 Care should be taken when cutting the crown When cutting the crown, care should be taken not to cut the base of the comb to prevent excessive bleeding and affect the normal growth and survival of the rooster. It has been reported that the size of the cockscomb area is proportional to the speed of heat dissipation. Therefore, in some hot regions of the south, care should be taken not to cut too much when cutting the crown to prevent the normal heat dissipation of the breeder rooster; the cage-raised cock usually used for artificial insemination is most often used. A good cut of the crown can facilitate activities and feeding in cages.
