![]() ![]() It should not have windows as direct sunlight can quickly heat up an incubator. It should be an area of low traffic, to minimize vibration, and temperature fluctuation. The room in which the incubator is placed is important. Ideally, before artificial incubation begins, the incubator should be cleaned, set up and running for several weeks to make sure it are working properly. ![]() Regular candling picks up early deaths and therefore eggs can be removed, giving infected eggs or egg debris less of a chance to contaminate the incubator or hatcher. Hands should be washed prior to touching eggs and ideally clothing worn around other birds should be removed. The incubator can be cultured to check for bacterial and fungal infection. The warm humid environment in the incubator is the perfect setting for harmful organisms to flourish and so the risk of introduction must be kept to a minimum. In the absence of disease from the ovary or oviduct, the egg is essentially a sterile package. They should be checked and calibrated frequently. Both thermometers and hygrometers can be placed around the incubator and in particular near the eggs. A fluctuation of just 0.2☌ can result in decreased hatchability. Problems with the actual temperature and humidity in the incubatorįaulty thermostats and poor quality incubators can lead to a failure to deliver the required temperature and humidity. Embryonic death can result from inadequate space in the air cell for pipping.ģ. This in turn interferes with yolk sac resorption and sealing of the navel. This results in eggs with small air cells and swollen chicks. On the other hand, increased humidity levels during incubation mean that insufficient moisture is lost from the egg. Low humidity in the first third of incubation interferes with the mobilization of calcium from the egg shell to form the growing chick’s skeleton and can lead to a stunted embryo. However, persistent or excessive low humidity in late incubation can lead to dehydration and kidney failure due to decreased perfusion of the kidneys with blood. If the humidity is too low and the chick risks dehydration, it can swallow amniotic fluid and any remaining albumin to compensate for excessive moisture loss. ![]() The embryo has some ability to compensate for differences in humidity, particularly in the last third of incubation. Humidity is not as critical as temperature for proper incubation. Those that survive to hatch resemble those that have been incubated at too high a humidity and have swollen, fluid-filled bodies. Too low a temperature leads to inadequate fluid loss. If the temperature is a bit high all through incubation, the chick is generally weakened and either dies towards the end of incubation or alternatively hatches small and weak. Too high a temperature then may just lead to an early hatch. Towards the end of incubation, temperature is less critical because the chick to some extent can thermoregulate. Too high a temperature at this time can kill chicks. Temperature, particularly in the first third of incubation, is critical. Better quality incubators have more sensitive thermostats, even air flow, a gentle turning mechanism and a smooth-opening incubator door to minimize vibration (which can be associated with early embryonic death).Īs a general rule, most parrot eggs are best incubated between 37.2☌ and 37.5☌ and at a humidity of approximately 56%. Solid-state thermostats are more precise and accurate than wafer-type thermostats. ![]() As a general rule, a fan-forced incubator is preferred over a still-air type as they are better at maintaining a steady temperature through the incubator. In the second type, air is simply heated. In the first, or fan-forced, type, a fan is used to circulate warm air throughout the incubator. Incubators can be divided into two types depending on whether or not a fan is used to circulate warm air. ![]()
