chicken bodies is more inexpensive
than using ethical
birds. Chicken bodies are also cheaper and
to get than
other types of birds, so this model offers an easier way to study the
Some
though, are that chicken
bodies probably don't have the same
and shape as living
birds that fly near airplanes. Plus, a chicken body launched from a cannon
won't
in the same way as a live flying bird. Because of
