I was sold my rooster, Kellogg, as a pure black "show quality" Orpington at about 3 months old. And that's exactly what he looked like at the time -- to my inexperienced eye, at least. Definitely solid black. As he's matured, I realize I was duped? Figure he's probably Orp but mixed with something. Any ideas? I'd like to rehome him, but want to give an honest description! Thank you!
