The nesting jar reduces storage space and its lug design makes attachment easy, while the low profile enhances stability. Jars are molded from durable, transparent polyethylene so the water level is always visible.Snap on base also permits quick and easy cleaning, as there are no threads to accumulate dirt and germs.
Pros - Nice size to carry, easy to clean , cheap.Great for birds in isolation.
Cons - None
I have 4 of these. Great size to add probiotics/ electrolytes to a hens diet . I use it for new chicks with marbles in the trough. Easy to clean and a great price , I add apple cider sometimes so the ability to clean it afterwards is important.
For young flocks or small ones this is great. It is fairly essay to keep clean. It also fits great in small spaces. The only bad part is it easily gets dirt or shavings inside the tray. Also the lid is hard to screw on sometimes. Overall it is one of the best investments that I have made!
Pros - Easy to clean, holds a nice amount of water.
Cons - It is light enough that chickens always knock it over.
I have 1 of these waterers, they work pretty well, though my other one broke because it sat in the sun, but that is my fault, not the manufacturers, I can clean it fairly easily, I do not recommend for full grown birds, because they will tip it.
