The reason why the pigeon does not hatch eggs

The pigeons may not hatch because they are not finished, or they may be bad in motherhood, or the environment makes it uncomfortable.This kind of bird can breed about 8 times a year. Two eggs will be produced each time. After the incubation of 18-19 days, the pigeons will break out of the shell. After that, the pro-bird will secrete pigeon milk and use it to nurture the pigeons.EssenceOn the fourth day after the shell, the young pigeons can open their eyes, but after two months of nurturing, they can leave the nest.
