After reading about Miss Prissy's styrofoam incubator my hubby and I made one! We got free eggs from a friend who obviously has fertile chicks. Her hens have several batches of their own chicks running around. I have no idea what will hatch, if anything. My friend has an assortment of chickens in her flock. But the surprise makes this fun. By the way, the humidity in my incubator is between 45% and 47%. I am trying the dry incubation. Are these numbers fine?
