I've seen there are few "chicken rooms" in zone , and my friend told me that those chicks have 4k HP for each.Who can tell where and how to get there?.
It is an easter egg level, like the cow level in Diablo II.
YOu can only do it in Multiplayer, and in it you will find the last boss of the Multiplayer map. Every chicken you kill drop a minimum of 2-3 rare/unique item.
Build a man a fire, and you keep him warm for a day. Set a man on fire, and you keep him warm for the rest of his life.
To the Righteous belong the fruits of violent victory. The rest of us will have to settle for warm friends, warm lovers, and a wink from a quietly supportive universe.
