Chicken Run On Slight Hill

We bought our place and it already had a chicken coop in place. I'm wanting to add a run to it on the side but it's on a slight hill.

So, I'm trying to figure out if I should dig out a trench so that I can make everything square or just place the wood on the ground as is and make up for the difference where the run will attach to the coop.

Also, what kind of wood would you use for this? I am especially concerned about the wood that will be riding on top of the ground or could be partially in the ground if I dig out a trench to make things level.

Sorry, I know it's just a chicken run but want it done well just the same.

I have chicken runs that are on fairly flat ground and they scratch the runs down and the outside edges build up
don't see any problems of being on a slope.
the wood is just regular wood has been down for 4 years with no problems.
wire is 2"/4" welded .
haven't lost a one in the run.

I'm surprised regular wood has lasted you so long.

Might be worth trying I'm just worried I'll have to do this again in a few years if I don't use green treated wood.

With mildly clever design, you could make the single bottom board easily replaceable without needing to replace any actual structure.
For example, you could build it in typical 2x4 stick construction with the walls sitting on a layer of plastic on a concrete pier block. This would keep the support structure dry from the ground moisture. Then you could put your siding on, stopping at the concrete blocks and then simply close the last few inches in with cedar or pressure treated wood (I strongly prefer cedar). Someday the cedar board will rot but at that time it will be a simple job to replace the bottom board.

Edit: rereading your post and I realize that you are talking about the run and not the coop. oops. I wouldn't worry one bit about leveling or squaring. I would use 'pointy posts' and just wire it up. No board on the bottom or on the top.

tried to add pic so you could see don't know if I got it
I built hoops with the wire with wood base 2ft/8ft just push them to gather move as needed
