It's a work in progress, and it's my first attempt at a hatch. I still need to build three more wire egg holders for the incubator (you can see the temporary egg cartons on the top tier). Also need to install window in the hatching compartment (freezer section). So far everything has gone fairly smooth except that on day 2 of the first set I pulled the probes to calibrate the controllers and forgot to shut down or monitor the heat. the cabinet shot up over 104 for about 20 min. don't know if I poached them or not but will candle in a few days. The incubator hold 90 eggs.
