How much time do deer spend in bedding area's?

With this project, I am currently recording data from several trail cameras placed in natural and hinge cut bedding areas that I have created. The goal of this research is to help myself and other hunters understand when and for how long deer spend actually bedded during daylight hours during the fall months. I have observed both does and bucks in bedding area's while hunting, but want to take this a step further and run several cameras in well used beds. This will let me record the time that deer bedded, for how long, and when did that deer get up. I will continue to update this as i get more data and pictures.
