Chicken Egg

The Chicken Egg item summons and dismisses a Prairie Chicken, a chicken small pet that follows you around, meaning it is a non-combat pet and will not aid you in battle.

Unlike most vanity pets, it is gained in a highly unusual method.

Every chicken you see in the game has a small chance of offering you a quest when you use the /chicken emote in front of it. If you cluck at a chicken enough, it will change from neutral to friendly. When it does, talk to it to get the quest (&tau;, &alpha;). Note that the exclamation mark does not show up above the chicken unless you are very low level. Also, once the chicken has been clucked at enough, anyone nearby that chicken can get the quest for the brief time that the chicken is friendly.



For your own sanity, it is strongly suggested you write a macro that does /chicken over and over to activate this quest.

The quest requires you to get Special Chicken Feed which you can by from Farmer Saldean in Westfall. Once you do, you can /cheer at any chicken (there are some near the farmer) and give the chicken the feed. The chicken will then lay a Chicken Egg, which you can take to summon a chicken at will.
