Yes yes! This is exactly what I have been looking for Perfect! Thank you so much! Van Dort in her book on Chicken colors says that show RIR color has the recessive black factor and that's one of the things that separates it from regular Black Tailed Red color. I have huge respect for W.H. Card. His book on "Breeding Laws" ( readable online at Hathitrust libraray) is one of my top 10 poultry books. Judge Card being Danne Honours' uncle's uncle and author of what Mr. Honour describes as the best article he's seen on the color Buff. Included in Honours' PDF compilation on "Buff Coluoration", titled "The True Gospel of The Color Buff". So now I see Card saying also Black is involved in making perfect Red. And also orange?!? That's a new one to me. I never thought of chickens as being orange. What do you suppose he means by "orange"?
Best,
Karen
Oh there are two more Card articles in this great book! I am reading one on Surface Color Diagrams now. So very helpful! What a great book!
ok so it seems the proper red color is balanced combination of the orange
( showing improperly in the pumpkin neck), the recessive black factors ,
and the true red? Am I even close here?
