I started with my chicks out on vacuum waterers and once they were out of the brooder and in the coop they were switched to nipple waterers. But my chickens didn't seem to be drinking as much and I worried about them and put them back on vacuum waterers until after the heat of that first summer passed. Then in the fall I switched back to nipple waterers only--I have two five gallon buckets with three nipples in each (one bucket in the run and one in the yard) and I also have my automated nipple system inside the coop. Again, I was very worried that they weren't getting enough water since they didn't seem to spend as much time at the nipples as they did the other waterers. Also, whenever I'd water a tree the darn birds acted like they hadn't had water in days.
So, I decided to figure out just how much they were drinking. I switched back to vacuum waterers for 5 days, putting one where each of the 5 gallon nipple waterers was located and emptying and turning off the automated system in the coop. I measured and recorded the exact amount of water consumed every day. I then switched over to the two 5 gallon nipple waterers again and measured the amount consumed every day for five days. I was surprised at the results. My six birds drank 2.75 cups of water per day from the nipple waterers and 2.5 cups per day from the vacuum waterers. Interestingly, the amount consumed was consistent over days. I really wanted a reason not to use the nipplesbecause of what I thought I was observing--and ended up convincing myself that they are, overall, better for me and for my chickens. It is ever so much easier for me to maintain a reliable, constant clean source of water with the nipples compared to the vacuum types. One of the best aspects of switching to nipples is that my chickens no longer have to share their water with the wild birds. Now, having said all that, the cup waterers look very interesting! If I didn't have the wild bird problems, I'd look into them.
