This might be my first time posting but I'm not sure, I have been reading the archieves and old posts for some time now. My question is, are red faced/throated indigos more common or are they just more sought after than a solid black? Do more people just breed the reds? As far as I can tell from the posts, there isn't any size difference and they're not different subspecies is that true? Is there a decent book on Indigos/Cribos?
