Building the coop on pavement?

[detz]

I have a large paved section that was probably used for a boat or something before our time but it's right where I'd like to put the coop so I could either try to dig it up or just put the coop on top. It's a little sloped so I'd have to use pavers or something to level it out but what are the pros and cons to putting it on pavement? Any issues with the birds digging at it? I guess it helps keep predators out.

In the picture you can see the bricks on the pavement, that's the outline of the proposed coop.

I have one that I built directly on an old slab and another that is adjacent to a slab (actually it's the same long slab that was an old machine shed pad.
Predators is one plus. The one on the slab is mostly for brooding chicks and storage for supplies and feed. I wall off part of it and put pine shavings down.
The other one is elevated so chickens can get under it and I keep straw or leaves on the concrete.
If you don't cover the concrete, the feces sticks to it like glue.

My coop is on an old concrete slab, and it's great. It is cracked and uneven, so I have stall mats on top to make cleaning easier and control dampness from the ground. We bolted 4"X6" treated timbers are base for the walls. Worked fine. Either level it out on top, or raise the slabs to level them? Mary

I would leave it crooked, if you try to level the concrete itself it will likely break and if you build your walls with a paver underneath to level the building at one end you are essentially creating a opening under your wall the thickness of a paver that predators will get in. Weasels and such will take advantage of any small opening like that

The building I put directly on the slab, the concrete was over 150 years old with big bad cracks and pitted terribly. I decided to level and smooth it out by adding a minimum of 2" of a topping mix to make it level. The result is quite smooth. It's been there at least 15 years and no cracks. It makes a big difference what you use to level it with.
If I had to do it over again, the only difference I would have done is to order buy premix delivered rather than use a mixer. It added so much time to mix it myself. The job would have been done in a quarter of the time. Time is money.

Thanks. The reason I want to level it is so it's easier to build (everything is even and square) and it would look better. I plan on putting a hardware cloth skirt around the coop/run anyway so the cap shouldn't matter. I could also fill it in with bricks too. I plan on using the deep litter method so now I just have to worry about everything sticking to the asphalt...
