A question, if I may? How long ago was the original SOP for the Delawares written? Is it fairly new? Or is this something that was written in the 1800's? I ask this because the answer may have some bearing on the conversation here. Please try to follow me, as I'm not sure I'm going to be able to explain this one properly. I'm going to use examples from experiences DH and I have had on a subject fairly far removed from Chickens. But I'm sure you'll make the connection.
Our home is situated in a remote part of Spokane County in Washington State. There are "junk" piles everywhere out here, and sometimes we find the darnedest things buried there. Yes, we love to scrounge around in old rusty junk heaps!
The average age of some of these piles goes back to pre-statehood times [1881 in this case] as indicated by some of the patent dates on the pieces we find.
Some of the things we find, absolutely defy explanation as to purpose or how it functioned. But obviously, a hundred and thirty years ago, somebody knew what it was, how to use it and when it was time to throw it away because it was broken or obsolete. In our collections from these junk piles, we've found pieces interesting enough to us to warrant taking them to our local farm museum for identification and explanation. Once in a while, they are as mystified as we are.
As the curator of the farm museum said to us one day...[paraphrased] "So much of the old ways from the old days are lost to us now. They knew what they were doing with this stuff back then, but as machinery was improved, that which was not efficient was left by the wayside in favor of the more efficient or labor saving devices. Sometimes the only way we know how something was supposed to work or what it was for, is through old owners manuals that somebody's great great great grandparents had tucked away in a trunk in the attic. Any time this information surfaces, it's absolutely priceless to us."
So, how does all of that relate to chickens and breeding and the SOP? Well, if the
original SOP for Delawares, just as an example, is something that was written a long time ago, it is possible that what was obvious to everyone at the time......so obvious that nobody thought it worth writing down..... has been lost in the dust of time. The green sheen may be just such an example. Perhaps back then, everyone thought: "Well of course there's going to be the green sheen. These birds were created from breeds X, Y and Z! What else would you expect?" Or the obverse may also be true.
Which ever the case may be, I have the distinct impression that it was of no major moment to those developing the breed at the time. If it had been, surely there would be some mention made of it in the original SOP?
..... Except for that whole "it's so obvious we don't need to state it" thing and the passage of time.
In which case, it's up to the breeders and showers, as Tim previously stated, to change it. Make a hew and a cry over something loudly enough, and the situation will likely be corrected in [hopefully] a reasonable period of time.
And such is my wish for my Delaware friends. That you all can have a definitive description as to the points of the breed standard, spelled out in black and while, with no ambiguity.
Boy! Jeremy, wouldn't it be a bummer if it turned out to be the opposite of what you're selecting for? That the green sheen is in fact a highly desirable trait?
