Your Blacks crossed with a Bronze create a Barred Black which differs from both varieties in color only. Breeding those Barred Blacks to each other then will produce 50% Barred Blacks, 25% Blacks and 25% Bronze. So you have not created a new breed with that cross, just a different color variation.
The Ocellated turkey is the same genus as the wild and domestic turkeys and is justifiably a different species. Being the same genus and a different species would not stop them from successfully mating and producing offspring although other than a study of Turkey Hybrids by
F.W. Lorenz, V.S. Asmundson and N.E. Wilson in 1956, I can only find anecdotal reports of your claim of the mating producing fertile offspring. That study was done back when the Ocellated turkey was considered a separate genus and species which has since changed and the Ocellated turkey is now also the genus
Meleagris.
For the purpose of domestic turkeys the APA did designate the breed as Turkey and recognized 8 Varieties. I personally agree with them and you apparently do have a problem with this designation.
