I have the galvanized metal waterers set up on blocks (and the heated base right now too). Here’s a pic of the one in the run - the setup is the same inside the coop but I’ve got a lap full of birds right now so don’t want to get up to take a pic inside. 
My whole setup is sand, inside and out. So it doesn’t matter if they get water on the floor inside the coop, it’s treated with water sealer and there’s a pond liner under the sand.
The chow is just in a rubber bowl. The feeders inside the run are Grandpa’s Feeders to keep the mice a little less well fed.
If you have anything other than sand inside your coop, you definitely don’t want it to get wet. A nipple waterer with cups might work. Jumping out of bed and running out to open the door at daybreak would be a lot less expensive and messy tho. If you have a secure run, that shouldn’t be a problem. If the pop door is open, the Flockers will head out into the run whenever they feel like it.
If you do decide to invest in an automatic door opener, I highly recommend the Pullet Shut door. They’re reasonably priced, very reliable, and easy to install. Plus, you can run them on a solar cell so you don’t have to have power in the coop!
