This tip is a little bit complicated to pull off, but the rewards are... well, the reward is a chicken. A kind of rare chicken that can normally only be gotten by the Alliance characters on your server.

First, find a chicken. Any chicken will do. Then, target the chicken and do the '/chicken' emote in front of it. If you're lucky, the chicken will briefly turn into a quest-giver and give you a quest. If not, then you have to try again. It's kind of rare, so you might be there for a while.

Then you need to work your way to Westfall, along with one of your Horde buddies. Just make sure that you have some way to communicate outside the game, since you can't really talk to each other in game.

Then, work your way to Farmer Saldean and buy the Special Chicken Feed.

Then find any chicken you like and do the emote '/cheer' at it. Give it the feed and:

Out pops an egg. Once the egg is spawned, anyone can pick it up, even someone who hasn't done the quest, including people on the other side of the war.

Have fun with your chicken.

Thanks, DakotaS96, for help with getting the screenshots!
