I have a dozen Delaware hatching eggs coming in the mail either tomorrow or the next day. I'm sending positive thoughts into the cosmos that my wee eggs are going to arrive unscathed. I have a still air little giant. Thanks to a breeder I spoke to the humidity and temp is running rock solid. Advice she gave was this: Take marbles or small stones(I used glass rocks from the craft store) anything that will hold heat and fill the large outside well in the incubator with them. Sterilize in boiling water and dry first. This prevents erratic temp changes. It is working like a charm. Been holding steady for 72 hours so far. I have hygrometer and two thermometers to confirm. Well I'm very excited to get my eggs. Will let them settle for a day and night before placing them in the bator. Anyone else incubating this weekend?
