Kelsos are very smart fighters. Unlike other gamefowl, Kelsos don’t jump into the opponents knives in the air, but shuffle and weave, or side-step before launching their own air attack.
The late Walter Kelso from Galveston Island, Texas. (a part of the lone star state with a semi-tropical climate), was a champion for crossbreeding.
To improve strains, in a time when most breeder folks fixated on the tradition of keeping their bloodlines as pure as possible, Kelso handpicked winning gamefowl to breed with his stock, something unheard of during his time.
