Deer here are in the soy beans every evening till late mornings. Around here if they get in the corn fields they have no reason to leave it so stay hidden in all those stalks that hold dew and rain plus the corn ears are still full of milk and taste sweet to the deer and give them another moisture source.
Once the corn is frost killed and the ears harden up the deer still stay in there as it is perfect cover till it is picked or chopped for silage. If you have a lot of corn in the area you will need to learn how to stalk down and thru the rows which Is a tough thing to do in 15 inch rows.
Yup Acorns are down and the deer could care less as the soy beans and corn is so much better. Soy's just don't provide the day time cover that corn does. the acorns are drawing the turkeys and squirrels.
A lot depends on the area as to the deer changing from summer to winter travel feed patterns.
In my area there just so much deep heavy cover other than the corn so till the corn is gone that is where most of them stay year round. What changes there patterns here is what crop is planted where.
Get rid of the coyotes any way you can trapping shooting which ever works for you.
