Let me start off I didn't know where to put this, so it is here
One of my roosters (I think he turned 4 years this February)is turning white in spots. He has just finished his molt and his new feathers have lots of white.
I'm pretty positive he's a NHR BO mix
One of his tail feathers is white at the base
I'm not sure if this is supposed to happen with age or some thing else.
He has just random half white feathers, not the whole feather the part closer to the body is white
Exception to his wing feathers, they are white with black at the tip. Also on his wings all this black came in with this new molt that added all this white also. Before this last molt he had a spot or two of black, now it is whole feathers that are black.
Like I said before I don't know if it's an age thing (the hens I got with him didn't do this) or if it is a genetic thing.
