Five black chickens began to lay eggs when they were raised for four or five months, and the annual egg production was about 180. If you want it to lay more eggs, you should pay attention to the feeding methods and feed different feeds according to different growth and development stages. Feed gypsum powder every day during molting, and add zinc to the feed, which can improve the egg laying rate. It is also necessary to add 10% fly maggots to the diet and feed them twice in the morning and evening, so that the egg laying rate will also increase by 20%.
