I believe the "The Fowl Player" achievement in Fable 2 is unachievable at this point in time. The only way to get the achievement in the past was by playing the flash game on fable2.com. Doing so would result in the chicken suit appearing in a chest in the Guild Cave within Fable 2 itself. That method no longer works. It doesn't work for me, and I have read posts from many people on various sites confirming that it doesn't work. There is another page on lionhead's site where you click a button to receive the items in a chest in the guild cave - that method also does not work, thus making the achievement unachievable. It is also now impossible to fully complete Fable 2 if you haven't already done so; the highest achievable gamerscore for that game is now 1340 out of 1350.
