To get the secret chicken quest (I think it was called "BAWK"; gives free prarie chicken) find any ckicken and do /chicken to it like 100x (helps to make macro featuring mutiple /chicken)
eventually its name will become highlighted in green and it will have a quest for you to get special chicken feed for it (it doesn't have to be the same chicken). To get the chicken feed go to saldean's farm in westfall and in front of the farmhouse will be a vendor/quest-giver, you buy special chicken feed from him, then find a chicken (there should be one near the vendor) and do /chicken x100 again to it and turn in quest. Chicken then lay egg, you right click egg, get prarie chicken.
