Has anyone used these adapter sets?

i love the feeders and my birds love them too ... installed 8 of these on a 20gal trash can and installed some with a slightly larger opening for my Jersey Giant and Bielefelder Roosters (their combs are so tall I was worried they might rub)
My Muscovy and Cayuga like using them too! I would not use another feeder for my adult birds, I love that there is zero waste!!!

I prefer the nipple waterer because my adult chickens tried to step on or sit on these cups and soil the cups with their dirty feet and/or droppings.

Ditto! Same here. Nipples are best and I put the feeders in a huge plastic tote with locking lid. Works great

I bought the same feeders and water cups on Amazon.
The feeder works great, but because the Amazon order for the water cups came late I had to grab the waterer seen in the picture from Tractor supply. I'm happy enough with the waterer I have that I haven't messed with the cups yet.
I was originally using Crumble in the feeder, and there was a lot of dust, so I've since switched to pellets. Also I make sure to cap the feeders every night after the chickens are locked in their coop.
For the money, the cheap Amazon feeders work fine and are easy to install.
