This is so interesting! I had no idea! The parents of the babies are mostly white so when we got two mostly brown (red) babies, I was surprised. And now this! The strange thing is that the dad also had much more color on his neck when we first got him back in June. Even the dad is getting whiter!It is common for grizzles, and other tri-colored breeds to get more and more white as they age. So your bird is quite normal.
Tiger grizzles hatch out nearly solid colored, but then they molt and have up to 60% white in them. It's quite amazing!
I had one hatch out with a lot of white. Once it molted, it changed big time!
They came through in a weird order. But the bird with the most color is the same bird with its first molt in.
