Does the single-stage incubator has a better hatching result than the multistage incubator?

Nowadays large hatcheries generally prefer single-stage incubators. Is it because single-stage incubators have better incubation effects than multistage incubators?

In general, if the same breeding eggs are put into a single-stage incubator or a multi-stage incubator, their hatching rate will not be much different. When the eggs are hatched in the incubator, they don’t generate heat in the early stage, and they emit heat in the later stage. The multi-stage incubator can take full advantage of this feature and bring the heat from the later stage eggs to the earlier stage eggs. This can greatly save power. This is the biggest advantage of the multi-stage incubator.

The biggest advantage of single-stage incubator is that it has better biological safety. Because now the incubator is getting bigger and bigger. Once certain eggs are infected by bacteria, they can easily spread to other eggs in the same incubator. Some hatcheries have encountered this problem. A batch of breeding eggs are infected by bacteria in the multi-stage incubator, the bacteria are transmitted to the next batch, and so on. The bacteria cannot be completely eliminated. In the end, the hatchery had to discard all the eggs in this incubator to eliminate this disease. The single-stage incubator has the eggs all in all out, so even if some eggs have problems, it will only affect this batch, not the next batches.

In addition, a single-stage incubator can ensure better incubation consistency. Eggs of different ages have slightly different requirements for optimal temperature and humidity during incubation. Multi-stage incubator, because the inner eggs are of different ages. It is difficult to create different temperature and humidity conditions for eggs of different ages in the same machine. The eggs inside the single-stage incubator are all the same age, so that the incubator can adjust different temperature and humidity settings every day according to needs, so as to provide the best temperature and humidity conditions for the eggs, and the consistency of the hatched chicks will be better.

And the technology like CO2 control, also will be more useful in a single-stage incubator. Because eggs of different ages prefere different CO2 level inside.

In general, the biggest advantage of the single-stage incubator is that it has better biological safety, and if it is used better, the single-stage incubator can obtain chicks with better consistency. The advantage of the multi-stage incubator is that it is more energy-efficient. In addition, if the user’s incubation scale is relatively small, and need several times loading to fill an incubator, the only option is to choose a multi-stage incubator. To choose a single-stage or a multi-stage incubator, the user can consider the above aspects.
