The get a Prairie Chicken as a pet, go to Saldean's Farm in Westfall and find a chicken. Select it and type "/chicken" into the chat window. Do this until a message appears saying "Chicken looks at you quizzically. Maybe you should inspect it?". It requires a lot of attempts to do this. If it is done correctly, when you right-click over the chicken it should open a quest window. Accept it and purchase the Special Chicken Feed from Farmer Saldean. Return to the chicken, select it, then type "/cheer" into the chat window. Right click the chicken and complete the quest. The chicken will now lay a Prairie Chicken egg who becomes your pet. Note: The quest is only for Alliance. If you are a Horde member, you can get the egg by having a friend on an Alliance account complete the quest and allow you pick up the chicken.
