And BTW, a short and simple web search yielded this:

A group of hawks is commonly referred to as a kettle, boil, or cast. These terms have been used since the Late Middle Ages and still have a place in society to this day.3 Hawks form large flocks during migration, taking advantage of rising thermal air currents. These swirling, circling flocks are called kettles.2 A cast of hawks is used to describe a group of hawks that are in flight, usually in a V-formation.4 Other terms used to denote a group of hawks include pot, an air pocket, and wake.

I guess there are not one, but SIX different names, used since the MIDDLE AGES for a group of hawks.

Once again for the slow, Red Tailed Hawks do not congregate together normally EXCEPT DURING MIGRATION. Even your own "citation" states this. So there isn't fields full of hundreds of them unless your anecdotal story was one where you catch every migrating "flock" as they stop exclusively on your fields.

Try doing some specific research on the Red Tailed Hawk. My citation:

Red-tailed hawks usually remain alone or in family groups, but they will soar together in flocks. Migrating hawks move by day, catching warm thermals high in the air.

And no one called you any names. But now I will. Calm down Karen...
