I think that the moving around in a short period of time may have made him a little territorial and putting the wheel in and out can upset a ham. As long as there are no drafts the floor might work. My Teddy is only with me for about 3 1/2 weeks now and he made a racket on every wheel I tried because he's really fast. I finally settled on the Wodent Wheel and I oil it with olive oil. Not a sound. I notice that Ted E. flings himself at the wheel, something my Patches never does. It makes his feet make noise. I also made sure that the bedding is under the wheel stand, not on the floor of the cage. It muffles any noise. Hope you find a solution.
