I have silkie eggs in an incubator. I have never hatched anything from day 1 before but I got eggs from a friend free so I figured I would try. It is a still incubator, I have it set to 101. I have different thermometers inside. One is reading 98, one is 98.6 one is reading 96 and one's is reading 100. Which one do I follow? Should I bump the temp up higher?
