So we have our incubator made from a...styrofoam cooler, glass for viewing, digi temp and humidity thermometer, glass bowl for water...we had a sponge but took it out (wondering why we need a sponge?) We donot have a fan so we have a still air incubator, the youtube video said temps should be 97-101...and humidity 50-70% but people here have been saying temps should be closer to 101 range... what is the ideal temp and humidity that we should shoot for? Can we put water on the bottom of the cooler? We had under the chicken wire but then I thought maybe after the chicks hatch we need to take the water out for them to dry? Could someone explain that part too? Do baby chicks need humidity after they hatch? If so what are those temps?
