Water cups comparison

[ngoko]

I've never seen or used drinker cups, I searched ebay for drinker cups and found the following cup types

This one

And this one

I know the first cup works by pressing that yellow thing but the second cup doesn't have that. How do they work.

The first type are expensive while the other one are not that expensive-, does this mean the second type isn't that good and reliable?

I need help comparing and buying the cups. I have about 150 chickens so how many cups do I need?

Thanks.

ngoko,

I see that no one replied. I'm guessing you found out how the 2nd cup works. I just happened to see how it works on youtube.

The weight of the water pushes down on the release valve inside the cup stopping the flow of water. As the chickens drink, the weight lessens and the valve opens up letting more water out. Pretty clever.

Those are really cool but seems like it would be pain to clean them out depending on how many you need. I assume they get stuff in them like regular waterers and also would get slimy over time. Otherwise, looks like great way to keep fresh water flowing!
