I just bought myself the 2x2 Dickey incubator - 2 turning trays and 2 hatching trays. My question is this: How can I have multiple hatches going? If I put eggs in once a week - how do I get proper humidity to the eggs in the hatching tray? I was thinking of spraying the eggs in the hatching tray with luke warm water - that way they absorb the water before it affects the humidity for the incubating eggs.. but so many people advice not to open the incubator. Please give me your thoughts/experiences!! Thank you!
