While watching how the red color blends with others i came across on:
What happens when chickens see red? Answer: They lay more eggs.
–A company* that markets red contact lenses for chickens (at 20 cents a pair), points to medical studies showing that chickens wearing red-tinted contact lenses behave differently from birds that don’t. They eat less, produce more and don’t fight as much. This decreases aggressive tendencies and birds are less likely to peck at each other causing injury. A spokesman said the lenses will improve world egg-laying productivity by $600 million a year.
