Red Sussex (You are saying a red fowl with "red" in the actual name, right?)
		
		
	 
Yes.  Exactly. "Red" in the actual name. Thank you!
 
I did manage to verify Red Sussex (1914) as being admitted to the APA standard as well as the Red Leghorn in 1929.
 
Red Cochins do not appear to have been admitted to the APA standard.  I can't verify their admission.
 
Buckeye Reds were admitted by the APA under that name (Buckeye Reds), but within just months or a few short years, the name was changed to Buckeye, which Nettie wrote about.  But they are not now called "Buckeye Red" by the APA, so they don't belong in this discussion.  The same goes for New Hampshires, of course.
 
Red Naked Neck admitted to APA standard in 1965.
 
While Red Silkies exist, I can't verify that they have been admitted to the APA standard.
 
But the following three chicken varieties are enough to go on:
 
Red Naked Neck
Red Sussex
Red Leghorn
All APA Standard varieties of chickens.  Good to know.
 
So, what this means is that a Red Chantecler and a Red Wyandotte, if presented for approval process, could possibly retain their respective names.
 
Thanks for the help, everybody!
