watering systems

[AZoverEZ]

I have read through several posts on the AZ thread about watering ideas. We will have a medium sized coop with 5 to 6 hens. I like the look of the water bucket with the nipples. That way we can put frozen blocks in to keep the water cool in the summer. Does anyone here in the Phoenix area have any suggestions or can end me links to previous posts? Thank you for your help. (There are so many posts to look through, I was overwhelmed!)
