Hope someone can help. Checked temperature because didn't see red light blinking. Thermometer says 87 and I believe it, as eggs feel cool and red light is not blinking. Eggs were put in Saturday. Can I save them? Might a broody hen be able to? I am wondering if it is the power source, as it feels very cool. Also, am wondering if I should turn off the fan, as it is blowing cool air on the eggs. Thank you for any help you can give.
