We're doing well keeping our humidity right now between 40-50% pretty easily, just occasionally adding water to the trays when the humidity starts to go down (we check it several times a day, but only need to add water every couple days so far) We are on day 8. Our vent is currently half open. I'm wondering what you guys do for lock down to raise the humidity for hatching? Close vent completely? Fill trays with water? I've seen mention of using paper towels to wick water out also... would someone please spill the secrets?
