Tarzan incubation equipment | new listing egg hatching machine | Tianjin egg incubator hatching equipment provided by Riko. We are hatching Equipment Co., Ltd. Shandong Dezhou Riko (www.ruikefuhua.com) at: Shandong Dezhou specializes in: automatic incubator hatching period, incubators, incubator, hatching brood machines, incubators, poultry incubators and other accessories are that under normal conditions of egg incubator hatching from eggs begin to hatch chicks hatched until the time. Different lengths and different types of poultry production use its incubation period is also slightly different: incubation period than meat-type duck egg-type duck longer. In general, the incubation period is 28 days duck: duck head tumor incubation period is 33-35 days. When the incubation temperature is high during incubation incubation period shortened; during prolonged incubation period of incubation temperature on the low side, hatched postponed. Hatched ahead of time whether it is delayed or are not normal hatch performance, more weak young ducklings, duckling survival rate is also low. Humidity: Humidity is also an important condition for mountain egg incubation period, if the lack of humidity, it will cause the embryo stick shell, hatching chickens hatched difficult or underweight, chicken feet scaly rough, dry specializing in the production of eggs hatching machine, if the humidity is too high, although heavier chicks hatched, but the chicken egg yolk malabsorption, abdominal, poor health, easy death, resulting in decreased survival. Hatching eggs of the mountain with two high humidity, the middle level is better new listing egg hatching machine, high-quality pre-humidity incubator eggs, eggs can heat well and evenly, mid-level, in favor of embryo metabolism, to the late hatching period increase humidity is to dissipate excess heat physiology, so eggshell loose structure, easy to peck shell hatching, pre humidity of 60% to 65%, the mid-55% to 60%, the latter 60% to 68%, hatching of 70% to 75%.
