second rut???????? never heard og it what is it?

I put in around 150 ish hours forrifle seasonin northern Indiana (laid off). I have seen zero deer. Nothing but birds and squirrels. Here is my thought processes there is no food within 3/4 of a mile of were I hunt. The fields are wheat that was harvested it just stubble in the fields. I don't know if I am doing anything wrong I am still pretty green when it comes to hunting.

Second rut is basically a hike in rut activity that takes place when does/fawns come in that did not get bred in mid-november and some chasing and seeking takes place. Not intense, but can be a great time to catch a big old buck being stupid again!
