One of my chickens, Roadrunner, does it everytime our lab Lil Spanky walk by her. Spanky always stops and touches her back with her nose, then looks at me as if to say, "What, is there something wrong with this goofy bird?!" One time, I had stooped to pat one of the 'dancers' and Spanky had seen me. The next time Roadrunner squatted for her, Spanky actually put her paw on Roadrunners back. I really watched that closely, wasn't sure just what the darned dog was gonna do, but she didn't claw or push, just kind of laid her paw there for a few seconds and then just walked away. Roadrunner still follows Spanky around and squats for her. Strange animals.
