Went to the garage to check on the chicks ( two weeks old tomorrow) and several were standing around an area looking at something. As I got closer I saw one peck at the something. Then I saw a chick half buried in the pine shaving. Thought they were attacking it because it had gotten injured somehow. So, I quickly reached for her and she jumped up and ran away. I was so puzzled at first. But as I watched I realized she was the first to discover dust bathing. Next thing I know a couple more are burying themselves in pine shavings. So funny!
