Westover, Maryland - March 20, 2017: To show their differing size, postures, and bodies, Dr. Bruce Stewart-Brown, the chief veterinarian at Perdue, let one of Perdue's conventional chickens walk among the slow growth chickens inside one of the chicken houses at the Westover Test Farm in Westover, Md., Monday March 20, 2017. The slow growth chickens are smaller, and more active than the conventional chickens, which have a larger appetite and are generally more sedentary.
The test farm hatches, houses, and offers a place to study the differences between Perdue's conventional chickens and breeds of slow growth chickens.
