Hi. I am wanting to hatch some mixed-breed eggs from my chickens this spring and I have some questions: 1. Do I need to spray the eggs at all with water? 2. When should I candle them? 3. What is the humidity supposed to be and how do I measure it? 4. What is the temperature supposed to be? 5. Should both of the ventilation plugs be unplugged? 6. Does water need to be in the bottom if the bator? 7. Should I only use eggs without poo on them? 8. How long can eggs be out before going in th bator and how do I store them? 9. Any more advice!
