I know there are lots of good ideas here for feeders and waterers because I've used a lot of them. Unfortunately, I don't have pictures available right now.
The easiest waterer is a 5 gallon bucket with sealable lid. Local bakeries use them for icing, etc. and either give them away or maybe charge $1. Drill 1/2" hole thru the side about 1-2" from the bottom, and seal the lid. I use a funnel to fill it thru the hole or plug the hole with a little stick or something and fill the bucket from the top then put the lid back on. Place the bucket into a larger diameter pan ( I use an old galvanized pan about 4" deep) and there ya go.
I put the one inside the coop on a couple of bricks to keep it out of the litter but the one in the yard is just on the ground.
I've seen this idea made with an automatic filler valve but haven't done that yet so I have to shlep hoses to the coop but thats ok. I only have to refill them once or twice a week,
