What seems to be the best bedding for the brooder as far as creating the least dust? We've finally decided to just brood inside since our weather can't seem to be consistent. I'm not concerned about the noise, only smell and dust. I plan to clean things up daily or multiple times daily, but want to help myself out by using the cleanest bedding possible. I've thought about puppy pads, but can't find any that aren't scented or free of an added attractant. Any suggestions?
