I’m so very fortunate that this recessive color has popped up in my racing homers. They are all down from my stock of Eisenhower, Golden Gaby and Black National from Mark Evans. As best I can tell, the common ancestor in all of these go back to a bird of Gaby Vandenabeele’s named De Bijter. Additionally, if you study pigeon color genetics, you will see a variant of recessive opal known as cherry among my pigeons.
