What to do if there is no fine egg under the breeding pigeon

There is no fine egg under the breeding pigeon to control the diet, reduce the feeding density, or change some young pigeons to breed.This bird can breed 8 times a year, and only two eggs will be produced at a time.Birds will hatch for 18-19 days, and the pigeons can break the shells. After that, the pigeons will secrete pigeon milk and use it to nurture small pigeons.On the fourth day after the shell, the young pigeons can open their eyes, but after two months of nurturing, they can leave the nest.
