I'm wondering, does it matter how much water you put in a moisture pan in an professional incubator. Will the incubator control the humidity, or do you have to put just the right amount or water in the pan each time and get a desired humidity?You can hatch in the bottom of a cabinet incubator. It complicates lockdown and adding new eggs if you set on a schedule, and the humidity ups and downs needed are a bit of a pain, but I have 2 little Ameracaunas in the bottom of my Sportsman right now that says it works fine.
Luckily, last night when I wanted to set the eggs for the week, the eggs in lockdown on the bottom had not pipped, so I opened the door and put them in. It might have been bad for the hatching chicks if they had not been a day late hatching and got a blast of cool, dry air.
I'd go with the cabinet and keep an eye out for a used "styrobator" for hatching. You might even want 2 if you intend to fill the trays with eggs, because 1 tray can hold more eggs than a hovabator can fit.
