Okay so tomorrow is day 18, do I lock down 1st thing in the morning or tomorrow night? Or does it matter ? I have been running humidity at 30 to 35 %. when I up it for lockdown will 65% humidity be okay? Too high or to low ? This will be my first hatch so I just want to double check on all of this. Any responses will be greatly appreciated. Oh homemade bator w/ fan if it matters.
