My nine banty chicks (Welsummers, EE's and Silkies) have been on aspen shavings since arriving from My Pet Chicken. At one week old I put a large pie pan full of sand from their future yard into their brooder box and within one hour two were giving themselves dust baths (how instinctual and precocious chicks are!). I also scattered some of their chick crumbles on the sand. In two days I had observed each of them pecking around the sand so I started adding very finely chopped carrots, broccoli, cabbage, beets, hard boiled egg, etc. to their diet. At two 1/2 weeks they all went to live in their coop with shavings on the floor. I'd bought a rubber round pan that a large water heater would sit in and that, filled with sand, became their dust bath site inside the coop. After one whole week in the coop I started leaving the pop hole door open all day...today was day 3 with the open door policy and although there have been several very curious excursions out the door they have yet to find their way all the way down the ramp to the warm and dry sand floor waiting for them in their yard.
I figure the sand/dirt/gravel from their yard has all or most of the tiny things they'll need to aclimate their guts to. The aspen shavings have worked wonderfully so far but I may put sand on the coop floor in the Spring after they are full grown...our entire 1/2 acre is sand so I have plenty for free. Maybe for next Winter I'll put some shavings over the sand just to give them something really "fluffy" to nestle into when the cold winds blow...just to make me feel better I guess.
