It is common known that eggs of young breeder flocks are better suitable for prolonged storage periods than eggs of older breeder flocks, because albumen quality in eggs of younger breeder flocks is higher. In practice, longer storage periods are sometimes unavoidable. A short storage period of 3 to 4 days seems to be necessary for a good hatchability. On the other hand it is also known that early embryonic mortality increases if eggs are set on day of oviposition. Despite of the climate regulation in the storage room it is commonly known that hatchability declines if the storage period is longer than 7 days. To prevent water loss from the eggs, the relative humidity in the storage room is kept between 70 and 80%. If the storage period is less than 7 days a storage temperature of 16 to 18☌ is advised and if the storage period is longer, a temperature of 10-12☌ is mostly recommended. At both locations eggs are stored in a storage room, where the temperature and relative humidity is controlled. After arrival at the hatchery, it normally takes a few days before the eggs are set in the incubators. Eggs are stored at the breeder farm before they are transported to the hatchery. Condensation of eggs should be avoided at all times to prevent bacterial contamination as much as possible!ĭue to variable market demands for day old chicks in the poultry industry it is common that hatching eggs are stored before incubation starts. During egg storage, egg contents change and the speed of change largely depends on the outside conditions.
