After doing some research on Roman and Byzantine Roman Chicken Breeds I found the Black Shumen, a rare breed used by Byzantine Romans and Bulgarians. Lets say as a hypothetical I wanted to produce a modern Roman gamefowl and I crossed it to the Roman Pit game the OEG and their dual purpose, the Dorking. It appears the Black Shumen is meant to have longer Slate or blue legs than the other two which have shorter white legs. Do the legs of this cock look slate or blue and how would one get the proper legs onto such a cross? Thank you.
