I am hatching duck eggs for the first time and I am really confused about all of the different answers. Is 100 degrees and 70% humidity ok for the first 25 days? Then from day 25 to 28 is 99 degrees and 85% humidity ok? Do I mist? Turn 3X daily? Do I have to let them cool for 5-10 min everyday? What do I feed them when they hatch?
