This is really interesting. My roo looked so white in the sink. There was not a hint of yellow in the skin, but I did notice the leg meat when raw was really red. Way more so than any store bought chicken I have ever seen. When I say the skin was tough I mean really tough, I gave up trying to cut through it and just cooked the legs whole with the skin on. I took the skin off after the bird was cooked and the cat loved it!
I had no idea there was such a variation in meat color among chickens breeds. I guess I should have realized that since different breeds have different egg colors! I never noticed the difference as a kid when we ate the chickens we raised. I think those were all Leghorns or RIRs.
