You can probably add some 'loveliness' to the chicken garden with some potted plants. I'd check the forums for what is and is not safe for your flock, then purchase some well established potted plants on the 'safe' list; leaving them in the pots for ease of replacement, if necessary. Not only will the plants themselves offer entertainment but will also offer them a place to be 'out of sight, out of mind' if they're squabbling with another member of the flock.
You mentioned that you're frequently watering the areas that they're pooping; be advised that wet poop smells MUCH worse than dry and the aroma is sure to attract flies. You might consider only watering it down weekly in the grassy areas, and spot cleaning your deck/walkway (2nd picture) as needed.
An inexpensive cookie sheet under the roost at night can assist you in removing the poop from their sleeping area by dumping their nightly excretions in the waste bin in the morning when you let them into the yard.
Also note that bored chickens might decide to peck at those shoes.
