True. I am grateful it is not the 1800s every time the furnace comes on in the middle of the night all by itself. And hot water comes out of the tap. And the toilet (indoors!) actually flushes. Which gets me up to what, maybe 1914?
But I digress.
You are right, you could use sperm from a superior cock from halfway around the world if that is what you want to do. And in the case of preserving - or reviving - a run down or endangered breed that might be necessary. The sperm bank project Piet mentioned is a good example of saving sperm from different breeds for preservation of those breeds.
On the other hand, using artificial insemination techniques on a regular basis - routinely importing the genetic material from elsewhere - runs the risk of eventually weakening a flock to the point where the local flock cannot be sustained without using the artificial procedures. Which is antithetical to the whole concept of most heritage poultry. It's not wrong. It's just something other than what most people think of as "heritage."
When I think of heritage birds I think of old breeds that are smart, good foragers, wary of predators, and capable of reproducing enough to maintain or increase the flock size while providing sufficient eggs and/or meat. If they happen to look like the pictures in the Standard at the same time, that's even better. That's what I'm aiming for. But that's just me.

Sarah, Respectfully. I cannot see where a flock would be weakened in any fashion. If anything genetically improved.. Top rams in Australia ( merinos) can sell for $50,000-- you can bet their semen is collected and stored and sold world wide. THe horse industry is world wide and semen is shipped all over and the result is better quality performance horses. I can pick a stallion to better match a mare-- single mating.
We imported the german new hampshire-- because from all I read here on this thread the german bird is far superior to the american bred. And is winning at the shows. Much of the world is breeding chickens, and while the SOPs don't always match up, the genetics are there. THe Europeans are way ahead of us in the breeding game IMO, based on what I have seen produced in the horse industry.
