I was looking for the pop bottle waterers when I saw th Mini Cup Drinker. Has anyone tried it? I did a BYC search and saw a post from 2009. Someone was trying to order it but there wasn't any info on how it had worked out. They are available in the US from Twin Cities Poultry Supply (http://www.twincitypoultrysupplies.com). This is a link to the manufacturer and has a video on how to install. http://www.bec.uk.com/mini-cup-drinker Thanks in advance.
