Coop floor space efficiency

I have been revamping my Coop setup to accommodate more chickens...🤣... I put up some "floating" roosts, and might do some other things as well so they can get up off the ground more but now looking at what I can change with my food and water. Some of the PVC setups intrigue me but then I read about how food gets stuck in them. The chickens free range our farm so they really don't go through a lot of food especially in the summer. They have also learned to drink out of our automatic horse waters around the Farm so I don't feel the need to keep a large volume of food and water out at a time. Although it has been quite convenient to just dump a 50 lb bag into my current metal trash can set up... But it takes up floor space.

What space saving things have you done? I know I can hang things and go vertical so just looking for ideas on what works and what doesn't. Picture of the current state of the coop. I still have them using a heated dog water bowl for water in the coop even though we are pretty well out of freezing temperatures.

I know there are going to be some who say don't put food and water in the coop, but since they are free-range chickens this is where it needs to go and where I want them to go if they need it specifically. The coop is also open-faced (with hardware mesh) in the summertime so there is no concern of humidity building up and what not. Dirt floor, mulch and wood chips put down for the winter and then deep litter method with hay scraps, but mostly leave it as dirt in the summer as they don't spend a lot of their days inside and it's easy to clean and drains.
