Ok I am not sure if this is a problem or not? I was bathing Moto today and I noticed a tiny patch just at the point of his shoulder that is missing feathers. He does seem to be going through a moult recently, he has lost a tail feather two weeks ago along with some smaller feathers which are just starting to come back in, all of this other feathers look healthy. He gets bathed 2 x week, and gets fresh air and sunshine 3 x week at least. Here is a pic, it was hard to get a pic of the spot, hope you can see it.
