I brood mine indoors on towels for the first week, which you can shake out outside then wash and reuse. There's no worry of gettting shavings in the food or water that way. I used shavings for a day on one batch of chicks and i'll never use them again. After that week I put them in rabbit cages with wire floors and drop pans. The feather footed breeds do much better on wire because it keeps their feet clean, and it is so easy to clean out because you don't have to interfere with the chicks.
