I am starting incubation of 12 chicken eggs on 5/20/12 evening. I got the eggs from local and some of them were sitting on the table for 3 days at 70 F. Hopefully I learned my lessons with previous homemade incubator experiment. This incubator is a styrofoam from kmart. Hooked up with a 40w bulb and a home made electronic temperature sensor / thermostat for automated temp control. I am going dry hatching route. For last 24 hours, the temperature is holding at 99.5 range. Feel free to join this thread if you started around 5/20/12.
