Humidity is one of four primary variables which must be controlled during egg incubation – the others being temperature, ventilation and movement (or turning). Humidity is the most difficult of the four to measure accurately and control and therefore is commonly misunderstood. Recent advances in solid-state humidity sensor technology mean that more modern small incubators will have digital humidity displays and active controls (Brinsea Advance and EX models) which help to achieve correct humidity.
The operator instructions that accompany all incubators give guidelines to achieve correct humidity levels for most species under normal conditions and in most cases this gives excellent results so please check that you have followed these guidelines. However there are times when incorrect humidity levels do cause problems and further steps are needed to check that humidity levels are correct. Whilst bird breeders have established norms for which humidity levels suit particular species there will still be some eggs that fall outside these.
