I use the DRY HATCH Incubation method. I have 2 large incubators (40 eggs each) with an automatic egg turner, heater & blower. I also purchased a digital hygrometer/thermometer from the Lawn & Garden dept at Lowes. My incubator is old so doesn’t have any digital readouts like temp, humidity, 21-day countdown like the newer models. So the hygrometer & thermometer (2 in one) helps me monitor the temp & humidity. The thermometer in my unit is just a regular thermometer and is NOT accurate!! On day 18 I remove the egg turner & put eggs on their sides and raise the humidity to around 70%. I have special bellows (like a big sponge) that I use since my unit doesn’t have water wells to add water in. When I remove the egg turner I quickly add a second wet sponge for extra humidity. I have to run my A/C during spring/summer because living in coastal Alabama (just north of the Gulf of Mexico) we have very high humidity generally 80-90% (I live fairly close to Danny & Wanda at Deep South Homestead) so our weather, temperature/humidity is usually the same. Running the A/C keeps the humidity down in the house (I incubate eggs in my laundry room that has A/C to keep the humidity down especially during incubating. During the 3-day lockdown, I close the vent in there to help raise temp & humidity levels. It is a lot of work incubating eggs here due to high humidity but it can be done.
