Keep the chicken house well ventilated to reduce egg breakage

Install ventilation machinery to keep the henhouse well ventilated, leaving no dead corners. The laying hens exhale more carbon dioxide in the high temperature environment, which leads to respiratory alkalosis on the one hand, and weakens the secretion of shell gland and decrease the deposition of calcium carbonate due to the decrease of carbonate in the blood on the other hand. The eggshell can not be fully formed, so the eggshell becomes thinner and the strength is reduced.
