Ms Nodolf:

As a veterinarian with many years of experience involving the care of chickens, I hope I can convince you that the planned 'chicken toss' in Ridgeland is inappropriate for welfare and humanitarian reasons.

Chickens are so-called prey animals. They instinctively fear being handled by those who they would consider predators, including human beings. This will particularly be the case with their handling and overall treatment in the 'chicken toss'.

Like all prey animals, survivability is enhanced by being able to avoid notice by predators. One of the means by which this is accomplished is by not displaying signs of disability where possible (4), even while enduring situations known to cause substantial pain or distress. As a result, some chickens subjected to extreme conditions such as in your 'chicken toss' may not show outward signs of being in distress. One cannot assume, however, that this means they are not enduring pain (2) or experiencing extreme fear as indicated by tonic immobility (4, 9).

Handling chickens by their legs or wings alone, as would be the case with inexperienced people such as the children participating in the 'chicken toss', would be painful in itself (3), but can also lead to injuries which exacerbate the pain. Ligaments can tear, joints may become dislocated and there may be other soft tissue damage. Some chickens may have a background which has made them more prone to osteoporosis leading to easily broken bones, causing additional pain (5, 7, 8, 10, 13). So-called broilers also have a higher predisposition to broken bones or painful joint dislocations (6, 11, 12).

These events also are clearly contrary to the principles of animal welfare put forth by the American Veterinary Medical Association, the largest professional veterinary organization worldwide, which states that animals "should be cared for in ways that minimize fear, pain, stress, and suffering" (1).

The chickens being subjected to this extremely stressful and terrifying situation gain nothing from it. They are not enjoying themselves. Furthermore, when people derive enjoyment at such events, they do so by debasing their own character by seeking thrills through violent acts against unwilling participants. Of great importance is the implicit message sent by such use of animals. Such events 'teach' children and others, by example, that it is acceptable to use animals for any human purpose, regardless how trivial and even when such use compromises the welfare and well-being of the animals involved.

Our society desperately needs to foster a greater respect for the other creatures with whom we share this planet. The planned 'chicken toss' is antithetical to that aspiration. I urge you to use your influence to discontinue this or any other use of animals that is unquestionably inhumane.
