Why do you suppose that they are called CHICKEN HAWKS?

This argument requires a bit of deductive reasoning but, I think your readers will agree, is iron clad. As a lad at Fairplay, my father did not sell eggs at Fairplay General Merchandise, he BOUGHT EGGS AND CHICKENS. As I recall, the egg man came from Russell Springs two times each week to pick up the eggs and chickens that my father had bought or taken in barter. Boxes of chicks would frequently come to the Fairplay Post Office when folks ordered them from Sears and Roebuck. Almost everyone in the Fairplay vicinity had lots of chickens.

At that time the pesticlde DDT was in general use. While effective on insects, it weakened the egg shells of raptors, including chicken hawks. This resulted in a precipitious decline in the population of raptors, including chicken hawks. The EPA subsequently banned DDT and, over time, the populations of raptors, including chicken hawks, recovered and are probably at or near colonial American levels. Concurrently, there are now almost no chickens in the Fairplay Community
