We use nest boxes like these for all our ladies but these have doors on the front. As the Chosen Ones enter to lay an egg, they trip the door so they cannot get out. We will come along every hour or so and release them once we have recorded who has laid the egg. This information is vital to help us decide which chickens to keep in our breeding program.  If you named one of the girls, you will be able to see how well your chicken is doing with our online running league table coming in the new year. Fantasy football has nothing on this.
