Crele is barring on a clean red duckwing. He does not have the duckwing patch so he is obviously on either E or ER.. basically a leaky black chicken- very typical of a black crossed with colored chicken or birchen(aka brown red, or the so called red copper as in marans).
The color on his hackles is most likely due to being Ss+.. in other words he's half silver half red. As in red duckwing crossed to silver duckwing, the roosters sometimes are called "Golden duckwing".. basically silver is dominant but sometimes the red pigment will show up anyways in varying degrees.
If he throws both red and silver daughters, that is proof he is half silver half red.
