So im incubating with flexwatt heat tape (12in wide, two single foot sections at 20 watts per foot) in an igloo type cooler with a Spyder robotics Herpstat-Thermostat. I have the heat tape actually set below the eggs running in a U shape up the middle of the two long sides. T-stat probe in the center of the bator on the floor. So far candling 9 eggs out of 19 (one was tossed because of a crack) are developing. This is a still air bator. Im curious what everyones experiences are with similar setups or bators that have the heating element underneath the eggs versus above. Ive never incubated chicken eggs, so im not sure what the results will be, but were almost half-way through so i will find out soon enough myself, but regardless, im interested to hear others experiences!!
