For my littles I just use a extra-large pan full of dirt that I put in their play pen. Usually that is plenty of dirt at a time and I change it out when I cleaned the play pen. I generally only raise 6 at a time - this year I lost one so I only have 5 in the littles pen right now - they have graduated from the play pen. Usually when they can fly to the top and sit on the edge they are ready for outside!! They are around 5 weeks old.So where I live it's still too cold for my chicks to go outside so can I take some dirt and sand and put it like in a container for them to dust bath in?
