Creating the Ideal Hatching Climate

The transfer of eggs from setter trays to hatcher baskets is routine in the hatchery, while the embryo continues to develop. In the final days of incubation, the embryo prepares for hatching and while embryonic growth slows down at this stage, the maturation of most of the organs continues. The embryo turns its body along

Hatcher Basket Hygiene for a Clean Start

The hygiene status of the environment into which chicks are hatched has a direct impact on day-old-chick quality and first week mortality. The first environment encountered by the chicks is the hatcher basket and its contents. Hatcher baskets are used intensively, often twice a week. Keeping them scrupulously clean between cycles will pay dividends. Weak

To Candle or not to Candle, that’s the Question…

During the incubation process, eggs are candled to determine the number of infertile eggs and eggs with dead embryos, together indicated as ‘clears’. This can be done as early as day 5 - 6 of incubation by an individual candling light, but it is time consuming and the risk of candling errors (e.g. accidentally removal

Adjusting Ventilation! Putting Science into Practice

Reducing ventilation at the start of incubation generally avoids the inlet of cold air. Because moisture is trapped in the closed incubator, the humidifier cold spot is also absent. Consequently closing the valves during the first days improves temperature homogeneity and heat transfer to the eggs, producing a good, uniform environment for continuing embryonic development and

Optimal Weight Loss Profiling during Incubation

Good hatchability is dependent on meeting all crucial incubation parameters. One of these important parameters is weight loss. Eggs should lose 11-13 per cent of initial weight during the first 18 days of incubation. Weight loss in hatching eggs is caused by the continuous evaporation of water from the eggs - and inseparably linked to

Managing Incubation Temperature to Combat Increased Early Mortality

As a breeder flock ages, the number of ‘clear’ (infertile) eggs increases as a result of decreased fertility and increased early mortality. Consequently, with higher numbers of clear eggs, a higher proportion of the heat produced by developing embryos in the fertile eggs is absorbed by the ‘cold’ clear eggs placed around them. Embryonic temperature

Finding Optimum Incubation Temperature

When a hatchery manager talks about incubation temperature, he or she refers to the temperature set point at the controller of the incubator. This temperature set point regulates the temperature of the air stream along the incubator’s temperature sensors. If the air temperature is too high or too low, the incubator controller adjusts the cooling

How Hatchery Management changes when starting Single-stage Incubation

Management in a multi-stage hatchery is based on a daily routine of setting eggs according to a strict setting schedule per setter type. The common principle for establishing a setting schedule in a multi-stage incubator is based on the need to transfer metabolic heat from more developed embryos to the less developed, heat-demanding embryos in

Storage of Hatching Eggs! Maintaining Quality

Egg storage is the time between oviposition (laying) and the start of the incubation process for hatching eggs. Optimal hatching results and chick quality can be achieved if eggs are set after an initial adaptation period of about 1 to 2 day(s). This allows carbon dioxide to be released from the egg, which increases albumen
