I read somewhere that you can use sand in the coop instead of shavings. I heard it was easier to clean and the chickens love it. Currently I have two large plastic containers with a large hole in the middle (kind of like a tunnel) so my chicks have more room. I am getting ready to upgrade to a large appliance box so they have more room as they are getting too big for the tote containers (did I mention I have 21 chicks). Currently we use pine shavings from TSC but I'm considering using sand in the large box instead of shavings. Would this be ok, or are they too young for that. I do have a bowl of sand in the brooder for them to play in, but they rarely get in it.
