You know this spring on e-bay some seller from Florida had an ad for selling 1/2 black shoulder IB eggs, said they had been working on this "project" for many years now, but was now willing to share their efforts thru egg sales of this "rare" b/s mutation. I called them out on this and got some very nasty replies back but the picture of their "project" bird looked identical to my regular-run of the mill IB barred patterned male who does have several solid black feathers as flights. I think for UPA to accept the new pattern you may or may not have I'm sure they want membership, and I'm sure there are many UPA members on here that can verify (I'm not a member)
