In Patch 6.1.0, the cooldown was reduced from 10 minutes to 15 seconds. The patch also had the -- apparently unintended -- change of being able to have multiple Robo-Roosters summoned. The latter was hotfixed on April 2, 2015.
A bummer, but at least I got to take screenshots of my rooster army (which are seen here).
