I have silkie eggs due in 2 days. They are from and top breeder and they were expensive and I REALLY dont want to screw up. I have them in a forced air incubator and I am worried that the fan will dry there membranes and then they wont be able to hatch. Help! Does anyone else hatch in forced air incubators? What do you keep your humidity? Will the fan dry there membranes out or?
