Venting? and lockdown

[CrazyChickens09]

When should vents be opened and how many? I'm going into Lockdown tomorrow and my incubator has two large vent holes at the top on the side and two small ones on the bottom on the other side. And is there any tips about adding moisture to the incubator once in lockdown

I would definitely follow the manufacturer's instructions on what to do with the vent holes during lockdown.
For me, I have a Genesis 1588 and keep the holes plugged up during lockdown since I want to retain as much moisture as possible.
When I add water during lockdown, I usually insert a straw into the vent hole and squirt water in that way.

It's a homemade incubator so no instructions.

Okay, so you really just want to keep the vents closed to lock in as much humidity as you can.
Keep the humidity at or above 65% (during lockdown) and you'll be fine.
Good luck with your hatch!
