My first thought on run design when there is pecking is can you make it bigger. That's not always easy or even possible. Clutter can greatly imp[rove the quality of what room you do have. Clutter means anything they can hide under, behind, or over (out of reach from the ground). Photos can help tell us what might or might or might not work. For example, a good way to do it is to lean a piece of plywood or a pallet against a fence (attaching the top so wind can't blow it over), but if your fence is electric netting that won't work.
You are trying to not create dead ends. You want the chicken to not be trapped but be able to run out the far end if it is chased. You want to be able to walk around in there. How important is pretty to you? Your neighbors might get upset if it can be seen and you junk it up, bringing neighborhood property values down. There is nothing wrong with building something that looks cute. The chickens won't care but you or the neighbors might. It often helps to have extra feeding and watering places available, preferably out of line of sight.
What do you have available? Pallets or old satellite dishes up on blocks are favorites. About anything you can lay down they can hide behind or something leaning against a fence or building. Perches high enough that the ones on the ground can't peck their toes can be good. A table might give you an elevated place to put food or water that the ones on the ground can't see.
What you do is pretty much left to your imagination.
