I am not expert on sheen, but my understanding is that black based birds on a gold base have a very strong green sheen while those that are build on a silver base don't. Does anyone on this group breed both Black Copper Marans and Silver Birchen Marans. If she can you get any side by side photos to show the difference in sheen?
My understanding is that the purple sheen is the result of a nutrient deficiency. Is that correct?
Having said all of that I know that the Green sheen used to not be allowd per the standard either. A breeder in Germany said in a publication that the breeders in his country would get some with out the sheen but they were never very good quality birds so the breeder just disregarded the no green sheen part of the standard and breed the birds the way their experience taught them that the breed should be bred. The Marans didn't get vary many high marks in the show so not many people wanted to show them favoring breeds that would win shows. Then the standard was changed to allow the green sheen and the Marans started to get higher marks and attract more breeders.
So...having said that an APA judge said that if he sees a bird BCM without the green sheen that it doesn't look right to him. So we have done a 180 deg turn on the green sheen from it being a defect to it being allowed to no where without the green sheen your bird is viewed as off or something missing that they can't put their finger on.
As for the purple sheen, it is something that they can put their finger on as being off and it will detract for the over all appearance of the bird in the eyes of the judge.
Yes, I agree that the purple sheen is pretty, I saw a photos of an all black bird (Ayam Cemani?, other?) that had a very vibrant mix of green and purple sheen among his tail sickles. It was a pretty cool photo, but even though blue is one of my favorite colors, if my skin were to turn blue it would not be cool because it would mean that I had an oxygen deficiency. So purple is bad not because the standard choose to go with another color, but because a healthy birds shouldn't have it.
