I recently started to notice that my American Blue buck has reddish brown patches on his sides. The fur also has a different feel to it. This is new for him and I have had him for over a year. I noticed it a couple of months ago and thought it may go away with shedding, but it hasnt. He also shed in chunks instead of loose hairs like the others. The guy I bought him from did have NZ as well as Americans. He said they were pure and I did see the parents who looked nice and blue. But now I wonder. Im selling these guys and want to know what Im selling.
