So after googling "poultry double breasted" I still am not sure what it means besides larger breasts. Is there a sure fire way to know if a breed is double breasted besides size like shape or something? I would like to start my own personal hybrids of bbw and midget white to end up with a smaller slower growing bird with around 70/30 white to dark meat like the bbw and bbb. Then spiral breed until they breed true. I am not interested in named breeds as much as fitting my needs although I will keep some pure mw's separated because I like the idea of real small turkeys.
