It could be a yellow skinned breed but feeding and pigmentation can change the colour of the skin.
As can the methods used in processing the carcass, varying the scalding time and temperature before plucking also can affect it and is often deliberately done.
Years ago I was involved in a lab trial involving chicken skin and egg yolk pigmentation through feeding and depending on what you feed them you can basically turn the skin and yolk whatever colour you like.
We had some lovely blue, green, pink, red, yellow and orange skinned chickens that were naturally white skinned and the same with the yolks.
although green and blue yolks weren't very appealing on the eye, they were nutritionally the same as any other egg.
we even managed a black yolk!
