I think I'm close to 250 run, maybe 50 ancient device found and I never got the Fowl Lair.

This seems to be the rarest of them all!

Found the divice maybe another 20-30 times and still can't get the portal to chiken world.

Anyone got it this week?

Just so you know, we did not change the chances for the Fowl Lair to appear in the Wheel of Misfortune. I have never found it either, but have only spent a fraction of the time searching for it that you have.
