Currently in lock down with 7 duck eggs. They should hatch within the next 48 hours. I have hatched duck eggs before. **My incubator is an Octagon 20 Advance * 1. How long should I wait to take the ducklings out of the bator? 2. After taking them out do they need food and water right away? 3. If they don't need food and water right away how long should I wait?
