RentACoop 5 Gallon Chicken Waterer with 6 Auto-Fill

The Verdict

If you’re tired of hauling a 3-gallon bell drinker out to the coop twice a day in July, the RentACoop 5 Gallon Chicken Waterer with 6 Auto-Fill cups deserves a serious look. This is a gravity-fed system that swaps constant refilling for a set-and-forget approach—and for most backyard flocks, it delivers on that promise. But as with anything that involves plastic threads and moving parts, there are a few things you need to know before you buy.

What you actually get

Out of the box, you get the 5-gallon reservoir tank, six individual drinking cups with float valves, and the tubing that connects them. The tank is a translucent white plastic—you can see water levels at a glance, which is genuinely useful. The cups mount to your coop wall or fencing with included hardware, and the water line runs from the tank down to each cup. The idea is simple: birds peck at the float, it releases water into the cup, they drink, it seals again.

Assembly is straightforward, but take your time with the lid. The threaded cap needs to seat perfectly before you tighten it; several Amazon reviewers mention cross-threading it and ending up with a slow drip that soaks the bedding. One buyer wrote, “Works great once you get the lid on straight, but the first time I filled it, I didn’t align the threads and it leaked everywhere.” Heed that warning.

Real-world performance

For a flock of 4–8 standard hens, this thing is a workhorse. The 5-gallon capacity is the headline feature—most users report going a full week between refills, which is a massive quality-of-life upgrade over daily topping off. The six cups also solve a real behavioral problem: with only one or two drinking points, dominant hens can guard the water. Six cups spread around the run means even the bottom of the pecking order gets a drink.

The float valves themselves are responsive. Birds learn the mechanism within a day or two, and the cups keep water reasonably clean since the reservoir is sealed. There’s less algae growth than in open drinkers, and you’re not scooping out pine shavings and chicken poop from the water every morning.

Where it falls short

The cold-weather issue is real. If you live somewhere that dips below freezing, the float valves can ice up and stick in the open position. That drains the entire 5 gallons into the run overnight, which is messy, wastes water, and leaves your birds dry in the morning. You’ll need a heated base or a plan for winter if you’re in a cold climate.

The cups are also rigid with slightly sharp edges. For standard hens, it’s fine. For day-old chicks or tiny bantams, the float mechanism can be intimidating, and the lip of the cup can be tough on their beaks. Several reviewers noted their chicks ignored the cups for the first week and needed a traditional waterer alongside it.

Who should buy this

This is for the backyard chicken keeper with 4–10 birds who wants to reduce daily chores and has a spot to mount cups at chicken-chest height. It’s also great for people who work long hours and can’t be home every evening to refill a smaller drinker. Skip it if you keep only two or three birds—a 2-gallon drinker is cheaper and simpler—or if you’re in a serious freeze zone without a plan for winter watering.

FAQ

Q: Can I use this for ducks or quail? A: Ducks will muddy the cups fast and can crack the float valves with their bills. Quail are too small to trip the mechanism reliably. Stick with chickens—standard and bantam sizes work best.

Q: How often do I need to clean it? A: With the sealed reservoir, you can go 2–3 weeks between full cleanings if you’re using clean water. The cups themselves need a wipe-down every few days since birds will scratch debris in while drinking.

Q: Does it work for a mobile chicken tractor? A: It’s heavy when full—roughly 40 pounds—so it’s not great for daily moves. If your tractor stays put for a few days at a time, it works fine. If you move it every morning, get a smaller model.

The Verdict

Buy it if you have a mid-size flock, hate daily water refills, and can mount the cups properly. The capacity and six-cup design genuinely improve poultry keeping. Skip it if you’re in a deep-freeze climate without a heated setup, or if you have a tiny flock that won’t justify the price and complexity.

Rating: 4.2/5 — A solid, well-designed waterer with one significant seasonal flaw and a lid that demands patience. For three seasons of the year, it’s the best gravity waterer in its class; winter is on you to solve.
