Exactly... There is an abundance of craiglisters in my area that sell gamefowl... It seems they are all obsessed with selling birds with names and leg bands. Instead of showing pictures of healthy birds they show a close-up picture of the legband.To add to what pc told you. Many Games have picked-up names along the way as a means to sell them. A good example would be Hatch chickens. These are named for one man, Sandy Hatch. When you look at all the birds called Hatch today and the variations within those birds you begin to realize that 99.9% is nothing more than a figment of someone's active imagination: names sell chickens. Pay little to no attention to names. Chicken people are only bested by fishermen when it comes to lying.
Two rules that will help you navigate your way through the world of chickens. Remember them and you'll be head and shoulders above the rest:
Rule #1: Chickens die.
Rule #2: Chicken people lie.
All Americans Games are a mix of something.... Asil, OEG, Wild Jungle Fowl... Etc... Just like American people (I am an American, but my dad is Russian and my mom is a mix of English, Welsh, German, etc)... but even Russians are a mix of Slavs, Nordics and Turks. Same with English (Anglos, Saxons, Celtics, etc).
Trying to keep something pure is contrary to the natural order of life. Strains are temporary categorization tools and thats about it.
Rule #3: Chickens evolve
