So, for me, the bigger question is whether horizontal nipples can deliver enough water for the hens during periods of extreme heat.
I've never read much about that being a problem and have been concerned about it myself during our heat waves.
Granted our heat waves are usually short lived and I usually put out shallow pans of ice water in the late afternoon anyway, they drink and wade in them.
...but...it can be difficult to train birds to the nipples, especially birds who are used to an open waterer.
Some of them just don't get it quickly. I did find tho that once they are used to it, they consumed the same amount of water from the nipples as from the open waterer.
I am able to determine this by measuring their consumption all the time with marks on all waterers and daily observation.
If you want to switch to a nipple waterer, I always suggest doing it during the most temperate part of the year.....
.....when it's neither screaming hot nor freezing cold as that's when dehydration can happen most quickly and be the most detrimental to health and production.
Monitoring water consumption before the switch and after can help assess the process.
Hope that helps.
