Here is an article from New Zealand about a baby chick which had four legs. Apparently it recently died because of digestive issues and they are now keeping it in a freezer before having it stuffed. So the question is have you ever seen a four legged chicken before? And how many of todays animals are the way they are because of a mutation which happened a long time ago. If you think about it they should get the DNA from this baby chick and see if they can clone it without the side effects. That would give you two extra legs per chicken for food consumption. Combine this with the featherless chickens and you'd have a winner.
Head over and read the full article about the four legged baby chick for yourself.
