You're singling out the chicken, but we've basically changed everything. Crops, vegetables, fruits... Compare the banana to the plantain for instance. People are so accustomed to artificiality, that their high-school biology never even kicks in to ask a basic question like "but if the fruit's goal is to be eaten so as to spread the seeds, what's the purpose of a banana that has no seeds?" To think of a banana with seeds sounds queer now, when it should be the other way around.
