Quote: I like the idea of adding dividers, but if you want to keep it one big nest and still add some privacy, here are some suggestions:
1. you can add a board that covers the top 1/4 of the front opening the chickens don't mind ducking to get in
2. you can use a hinged door that covers up half of the boxes and opes up
3. you can use two hinged doors at each end that open like barn doors but with a gap in the middle to cover all but the center foot or so of the box.This would allow your chicken to enter and decide if it wanted to lay in the left, right or center box. The center box would be no more private than your current setup and you would be able to tell which way your chickens prefer their box.
