Non-Gamers' Guide to This Post
Pets: You can get small, useless pets that look cute and follow you around in Warcraft. You get them a variety of ways, through quests or vendors or rare drops from monsters.
These little pets have nothing to do with the kind of fighting pets you can get as a hunter. These are just decoration.
I got a chicken. Not so much because I wanted it as I wanted to see if the quest to get it was real. Because here's the thing: You have to cluck at a random chicken (/chicken at any random chicken in Westfall or Elwynn) many times in a row to get the quest.
Yes, you heard me. You have to find a chicken and make a fool of yourself at it to get the quest. The end prize is your very own chicken, and you're only out a little dignity and 25 copper at the end of the quest.
Here are screenshots. This way you know I'm not making it up.
Tip: The guide I randomly came across said you have to cluck around 60 times, but he was lagging badly. I clucked around 15-25 times and it worked. So try to do it at a low-lag time.
Tip: Make a /chicken macro. Go into your options menu, click "Macros" and make a "New" one. Then type /chicken into the big blank box and save it. Drag it onto your task bar and click away. Saves you a lot of typing, and you can delete it afterward.
