8. Adjust the humidity levels in the incubator. Humidity should be around 45 to 50 percent throughout incubation, except during the last three days when you will want to raise it to 65 percent. You may need higher or lower humidity levels depending on the type of eggs you wish to hatch.. Record the day and how many eggs you've incubated on a calendar. You should be able to estimate your hatch date based on average incubation times for the bird species you want to hatch. For example, chicken eggs typically take 21 days to hatch, whereas many duck varieties and peafowl may take 28 days.
Therefore, do not store eggs more than 7 days before incubating. After 3 weeks of storage, hatchability drops to almost zero. Plan ahead and have a regular hatching schedule to avoid storage problems and reduced hatches. Allow cool eggs to warm slowly to room temperature before placing in the incubator.hen hatching, the humidity is increased to 65% relative humidity or more. An excellent method to determine correct humidity is to candle the eggs at various stages of incubation. The normal size of the air cell after 7, 14, and 18 days of incubation for a chicken egg is shown.
