Lisa, The Wheaten males should not have the white tail coverts at the base of the tail. It is possible to breed this white out of the Wheaten.
this is good news, I have about 7 boys and all of them have this trait and very few without it. I also found that
my wheaten boys have terrible slow growth on their tail feathers,but the ones who feathered late have less white fluff.. i was going to avoid using the
slow growers, would you advise to reconsider and give them equal consideration to whiter tail fluffers?
