Four birds. When I let them out of the coop into the run in the morning, they all run to the feeder and two or three can fit comfortably to chow down, and they spill a lot in the process, so one usually eats off the tray (placed there to catch food and make sure it doesn't get mixed in with the dirt) The water is flowing freely, and they seem to be drinking fine from it- I try to adjust it if it's at an angle that makes the water level low. I'm working on my grit and shell setup- so far they've knocked over everything that I've tried to use, mixing all the grit and shell in with the dirt. I'll try some different methods. I'd like to get a proper feeder, but at the moment all of my spare cash is going to Christmas gifts. I'll make another milk carton one.
Oh, they can make a mess LOL
You don't have to do anything fancy. If you have a couple of shallow cans like tuna cans, you could screw those on either side of a post in the run to hold the grit and oyster shell, just make sure the cans don't have any sharp edges. You could do the same with a small roundish plastic dish, etc.
I like using zip ties for things too, you may find a way to attach your containers without having to use screws too?
