i didn't take the time to read all of the posts, so this may have been covered already. we had the same problem. when our chicks were 2 weeks old, i moved them out of the rabbit cage into a large storage tub that's 35"x21". since it's solid sided, it works well to keep the shavings inside and not flying through the walls like the rabbit cage. also, i had some leftover blocks from the coop project that i stacked under the feeder and waterer to get them off the floor. this helps to keep them cleaner, but i still find shavings and litter in both. not sure it can be stopped entirely until they're big enough to move into the coop and get the food and water well off the floor.
