I am new to this... Currently I have 7 guinea fowl (given to me as month olds) and am looking to hatch some of their eggs. I would be interested in gleaning information from all the wise people on this site.... First question - I have made an incubator from a Styrofoam cooler, heated with a 25watt bulb hooked up to a hot water heater thermostat. My thermostat is fluctuating the temps between 85.6F - 107.2F how do I regulate this? would it work better if I hooked up a fan? is there something I am doing wrong? Any advice would be appreciated.
