So I have like many others lost faith in the hovabator. I have never gotten over a 30% hatch and it’s time to move on. Hopefully some folks who have built before me can share some insight. The starting unit is a full size side by side refrigerator. I already have the following in hand or in route: 1) The refrigerator 2) Herpstat 2 dual control proportional thermostat 3) (2) Brinsea Spot Check thermometers 4) 12” by 96” sheet of clear ¼ inch lexan (thinking door windows) 5) water wigglers or as they were labeled water snakes Other specific items on my list 1) Ceramic heat emitters (light bulb types) 2) Misc light sockets, switches, etc My first decision point is hatcher vs. incubator. For humidity and sanitary reasons, I know that I want to hatch outside of my incubation unit. This explains the dual herpstat. I know the larger previous fridge side of the unit will be the incubator. The other options are: 1) Let the entire freezer unit be the heating chamber with my bulbs. Pros: Fan is already configured to rotate air through that chamber and into fridge with minimal modifications. Cons: That’s wasting a lot of space for heating and I have to build or acquire a separate unit for hatching. 2) Divide the tops of each side (freezer and fridge) and create 2 heat chambers. Let the larger fridge side incubate and the freezer hatch. Pros: All one self contained unit. Cons: More complicated design for air flow, less space for eggs to incubate (I suspect still plenty to hatch given rotated setting dates). Lets hear your thoughts!
