I'm breaking the mold here

I have no experience with nipple waterers for birds so I can't say either way but they are very popular with the folk here so can't be bad!
As a new chicken owner, my only experience being that of my dad and extended family, I used buckets and gravity waterers, but scrubbing them weekly is a pain in the A and if I didn't the algae built up pretty quick. At that time I couldn't see how a chook could get enough water from a nipple in the hot Australian summer unless they stood there all day, so after some research I went with cup waterers, for me it's the best of both worlds, I do have to rinse out the cup when I fill them but otherwise no cleaning required. I now understand how the nipples work but I'm happy with the cups and my chooks are too so I "don't fix what ain't broke" as they say

I got mine from an Australian company but I've seen them by other people on
eBay if you search chicken waterer.
Not the best photo but you can see them in the background just hooked on a bit of fence,
I have more chooks now so will probably upgrade to a bigger water drum with more cups in summer, the PVC pipe is good for small flocks though, these 2 last 2-3 days for 8 chooks in winter
Also since you asked about feeders I'll include a pic of mine. Always have them off the ground somehow or you'll end up wasting half your feed. These ones work fine though I'd love to experiment with other styles if I get the time
