Generally, they lay eggs on 10 ~ 15d after mating, and pay attention to keeping the environment quiet. Two days before laying eggs, put hemp chips on the egg nest or put some clean short straw or pine grass as long as pigeon hair in the egg nest, and record the laying date. During the incubation period, the rain should be prevented from showering people, and the padding should be replaced in time when it is wet. Usually pay attention to check whether the egg leaves the belly feathers of the parent pigeon to prevent the egg from being cold. In hot weather, we should reduce straw mats, open more windows, cool down with cold water or spray indoors. When the temperature is low, pay attention to closing the window, increase potential substances, and prevent eggs from freezing to death. Take 1 photos of eggs 4~5d and 12d after hatching, take out unfertilized eggs and dead embryo eggs in time, and combine the embryo eggs with the same or similar age for brooding and feeding, so as to reduce the burden on some parents, make time for rest and produce the next nest of eggs in advance. During the period of 17~ 18d, check the larval condition. If it is difficult to break the shell, you should manually break the shell for midwifery.
