First, the proportion of male and female hens should be appropriate for the average male and female chickens: 1:15-20 for egg-type chickens, 1:12-15 for dual-use chickens, and 1:8-12 for meat-type chickens.
Second, adjust the age structure of the flock Because the fertility of new chickens raised in the year was relatively high, the fertility rate of old hens was relatively low. Therefore, the number of new hens should account for more than 70% of the number of chickens.
Third, when raising chickens is not allowed to breed in large groups, it is better not to exceed 300. When there are too many loose-breeding chickens, it is necessary to expand the playground accordingly so that the chickens can spread their activities and perform breeding to increase the fertility rate.
Fourth, to strengthen feeding the rooster can be hung on the wall or in the cage with a higher food waste (the height of the trough is better for the hen to eat less than food), which contains high-energy and high-protein mixed feed, such as Cornmeal, fish meal, silkworm meal, bone meal, etc. Green feed should also be fed regularly.
