How do we deal with breeds/varieties that have gone extinct but are still in the Standard (Lamonas,Brown Cochins),and varieties that were in the Standard but were dropped,but still can be found? Are they still not old?I recall seeing Dominque/Cuckoo Leghorns in very old Standards. Rose Comb Buff Leghorns and Single Comb Pile (Pyle) Leghorn,were both dropped from the 1928 Standard. (these were all largefowl in the APA Standards. I asked the rare breed conservancy how they deal with Breeds that are common,but have varieties that are very rare,like Buff Leghorns,Red Leghorns or Columbian Leghorns?The answer was they are not important,as they could be recreated.With this line of thinking we can completely lose a lot of varieties,as not important,then re-invent them. I know most people would not bother.The time,effort ,expense and work to recreate would be huge.The level of skill to do so,is beyond many breeders ,even if they desired to re-make.
