Those looking for some more information on their chickens and the coops they are in will be delighted to hear about the new FarmVille
update. Chickens are broken into four categories: white, brown, black, and golden. Those that use the "Look Inside" feature on the coop will now be able to see how many chickens they have, what the chicken types of those in the coop are, and what mystery eggs do... sort of. This update was rolled in with the addition of the holiday items, which means that you can see the effects in game right now.
