OK - so no eggs, no pre-lay sheds yet, and I don't believe I've missed ovulations - but anything's possible. I do have glowing on two of my girls.

So:

Incubator - check
Incubating tubs - check
Hatchrite - check
Helix - check
Water bottles - need to get

When do you guys first fire up your incubators, and do you fire them up with tubs filled with the incubation substrate or without? I don't want to fill mine too early and risk drying out the Hatchrite if it's not necessary.

What do YOU do to make sure everything's functioning properly?
