Quail normally shy away from climbing. You might get a few who will use a ramp, but most wont. If you don’t have this coop already, I strongly recommend against it. These prefab setups are usually very flimsy. I bought a prefab coop and run when I started out, and I ended up spending an extra $70 and an entire afternoon strengthening the setup. I reinforced every joint, zip ties the hardware cloth onto the wood because it was just sloppily stapled on and loose in many areas. The wood does not stand up to weather, so I have to keep a tarp over it if it rains, even the indoor coop house. It leaks, and if a stray dog jumped at it, they would certainly damage it beyond repair.
My suggestion is to just build your own ground pen with pvc, hardware cloth, and zip ties. It’s sturdy and cheap, and any places that start to wear can easily be replaced.
