For al mine, watering cups.
Here's a link to them in action:
I got them off eBay for under $20.

I like that they are float operated rather than bird-controlled. I have a couple who think running over water is just a glorious thing and mud is fun to scratch in.
It can be set up on a low pressure system like a 5 gallon modified bucket. They tend to stay clean with just a bit of debris now and then. Cleaning is a simple wipe out, and I can just refill the bucket when it's low. Then they are never out of water.
