Daisy chain 2 thunderbolt displays by direct connect

I was hoping to hook up 2 thunderbolt displays to a mac mini. With the way the screens are set up, they will be nearly 6' apart from each other, which makes connecting the pigtail of screen two to screen one impossible. I havent' been having a lot of luck with finding reviews of reliable extention cables that are known to work, but I have been seeing a ton of thunderbolt to thunderbolt cables (6' and 9'). Is it possible to daisy chain from the 1 open thunderbolt port on display one to display two and leaving the pigtail detached?

Thanks!
