Yesterday when I was checking the food and water, one of my Production Reds was waiting her turn to lay. The favorite nest was occupied by a Leghorn who was clearly ignoring the fact that the box was in urgent need. The PR stands over her and begins poking the eggs that the Leghorn was sitting on. Still no response. The PR starts spinning in circles, then going back and forth, standing over the Leghorn again and then spinning again. Occasionally she would stop and check out the other nestboxes, only to start the behavior all over again. This behavior continued until the Leghorn decided she was done and got down. I didn't even have time to grab the eggs before the PR was in the nest. I saw her do this same behavior the day before. It so reminded me of a ladies room when someone is occupying the only toilet with toilet paper and someone else has to go really bad. Are there any other OCD hens out there?
