My kids will have to walk their bikes through a thin area between the run and the house, we don't want any scratched up legs or popped tires.
My husband doesn't think we have mink here, but who knows. We do have a raccoon and opossum problem. We frequently see dead opossums in our neighborhood streets. Do opossums dig, anyone know?
Chickielady, I think that's similar to what my husband was talking about doing. My SIL gave us a huge roll of 1" chicken wire that had been left at her home by previous owners, which we are not using on the run or coop. We have 1/2" hardware cloth for the run and 1/4" hardware cloth for the coop. He was planning on cutting it to size, then putting a thin coat (1/2") of concrete mix over the top. The wire would be the predator proofing and the concrete would keep the chickens from hurting their feet as they scratched and dug. He planned to fill the floor back in with screened dirt and whatever ground cover we end up choosing.
Fortunately, digging out the area won't be too difficult. It's more a matter of smoothing it out. Whatever we choose, ground work has to be done. There's a significant hole in the area already (which is what gave my husband the idea). With our children's blessing, we reclaimed our children's digging area for the coop/run. They actually had the area pretty well dug down because they were trying to dig to the other side of the world. 
ha ha ! One their way to China were they ?
So far, we have 3 coops, each is a duplex but one, which is a Triplex.
Each has a run & all 3 are different.
The last one we built is up off the ground, kinda on stilts, with area underneath for chooks to hang out & has a dust bath under there.
That is the best way to build a coop !
The other two are inches off the ground on piers, which allows all sorts of critter to live underneath.
The surrounding pens aregreat to keep out possums & coons and yodel dogs and BobCats...but the rats can live UNDER those 2 coops, so that is why we buried deep wire.
But the Mink went down under it ! 
And tried dragging a pullet with them.
Imagine seeing a hole under the deep wire with chooky feets sticking ot !
WTH ???????????? As if someone shot a chicken out of a cannon, straight down into the dirt along side the fence. 
Thus the concrete.
We simply dollied bags in, open the bags, and sifted a 2-3" "curb" ON/next to, the wire.
I will send ya pics if you want.
They (woozels) cannot dig through cement.
