Sounds like you are doing a great job with him! It is normal for a bay/black to clip out looking almost silver black. Their color usually returns later (though i'm not sure your boys will since he is ready for winter). I am still at bay sabino-i do not see silver.
Take a look at Joanne's horse on the second page of this thread-it shows what sabino does!
