3. The rut hits the same time every year: November 10
Throw out weather, moon phase, and the Corrioulos effect. Deer are going to do their thing no matter what, and that's going to happen on 11/10 up here in Saskatchewan. Now, other factors might limit how much of the rut you witness from your stand (for example, unseasonably warm weather is going to make most of the action at night). Also, it's common to see some types of rut behavior, like a younger buck chasing does. But, these chases are more out of curiosity, not the urge to breed.
