Cackle is the middle man and not where the actual poults come from. I had a discussion with their Royal Palm supplier when Cackle had pictures of Tri-Color turkeys posted as being Royal Palms.
That is another thing that should have tipped you off. There are no true Spanish Blacks. If Cackle were doing the right thing they would not make the false claim that they are Spanish Blacks and would simply post them as Black turkeys. In the U.S. Spanish Blacks haven't actually existed for many years. They sell any black looking turkeys as Spanish Blacks irregardless of their lineage. Overseas some places call anything that has any black a Spanish Black including Barred Blacks.
Your one poult may well be a Black turkey but the one with the gray areas will not be a pure black turkey,
The other poult might be a Bourbon Red.
