I just bought two feather dusters the other day. I had been watching them in the store for about a week. They looked good and healthy, reacted well. They were joined together and embedded in the sand when we got them out. So I found a nice spot for them up in a rock and easy access to the sand bed if they prefer it over the rock. One is out and doing great, the other has not shown since I brought him home. I looked all over the tube its in tacked no damage. But he's all the way at the bottom of his tube and was out about an inch this morning from the bottom. So I readjusted them again so that they would have there pick of rock or the sand bed dig a fighting hole in and left them be. It looks like he is even further out now. Not sure if he is skipping town and looking for a new spot to make a new tub or just fortifying there position while the other stand watch...lol I never saw him loose his crown so far. So kind of lost as to what might be going on. Any advice out there?
