No, the incubator is on my tower roof, near the chicken coops. It has worked properly in the past, and is properly secured. I do grow plants, but only in backpacks (with the exception of the garden plot that is also located on the roof, but far away from the incubator). I'm going to try taking the eggs out and resetting them to see what happens. If that doesn't work, should I try relocating the incubator?
Addendum: The incubator is on one of the extending wings of the tower roof. Could that be affecting it?
