Moo, I've never had a partridge anything I have no idea how they feather out. As a chick he looked a bit like a black and white cat, or a calico cat. He was not a solid black peep. The breeder mentioned he might be mottled. Then as he grew he turned all black. Until recently. He has this bright copper all around his.neck and now in his top knot. I will have to research the partridge. I had intention to.work with partridge. I could order some eggs I suppose.
