ok lockdown is tomorrow for my first hatch i have read here tht the humidity should be 80% and leave the temp as is. So i will be adding water to both of my trays on the bottom of my bator (Hovabator1620n with a fan) and i know not to open the bator until after hatch has completed. My question is this....will there be a need to add more water to the bator over the next 3 or 4 days to keep the humidity up? If so ..how do i go about tht without opening the bator lid??
