So, I have a chain link dog pen, unused for a few years

The ground is just plain dirt. Do I need to put anything down over that? There are some mole holes that appeared in the last week or so. I was planning on some sand under the coop, and bedding under the 'big' roof.
If there is nothing to worry about, just give me time.
So let me know what I need to know (I am already pretty sure that 4 is not enough)
