I bought the 4 tier quail cage which came with water rods with nipples. However, the style that was included with the cage were "push UP only" and from one direction (directly underneath). I tried for FOUR days to get my quail to drink from them and it just wasn't working at all! They would peck at it from all angles EXCEPT directy underneat and got zero water. I knew they weren't getting any because there wasn't the standard drinking motion AND more than a 5-6 times a day I would go out and show them how to work it and they all ran to the water when I released it (if only 1-2 came then obviously the others weren't thrist but to have ALL of them run to get water meant NONE of them were getting water). Finally broke down and ordered these. You can push from left, right, back, front or underneat and it releases water. The minute they were installed all of my quail were successfully drinking from them and visually obtaining water. I have no idea why these don't come standard with the cages. (Hatching time suggestion.....add these as "standard" with the water rods) No learning curve needed.

I purchased these to add additional nipples to the water pipeline. I had purchased ones from my local farm store and even Amazon, but these are superior.

Gives water better than just the up and down Nipples.
