Any suggestions on what to put down on top of it? Just straw? I will have a box in one corner that will contain dirt and I am planning to buy some pieces of sod to put in the run. I am sure the grass will not last very long though! I was just wondering if there are others of you that have your chickens on just decking and how that has worked for you... Thanks in advance for any input and advice! Cluck, cluck.
