I have 10 2+ week old chicks in the bathtub. I had the chick starter in a bowl down at one end. Tonight I moved it to the center of the back wall. This chick (the shyest, most timid one) jumps up on the bowl, and takes a "dust bath" in the feed, falls off, and continues to have a dust bath in the shavings, then gets back up on the feed dish and does this several times. I have never seen anything like this, not scratching in the food dish, but actually doing the dust bath thing. Any explanations?
