I do agree fundamentally. Though Lately it would be up for debate. We didn't know we needed an Iphone until it was released. I don't think that we knew we needed a cornish cross until we had it. Reading the history of chickens, lots of people were trying to create a better chicken. But it seemed that the chickens were just fine for most people.
Many texts point to heritage birds being king, and dieing out or being severely neglected after the cornish cross. Big time super markets cam about at the same time, and they needed meat for the store. The demographics and culture changed big time around WW2 in all aspects.
It is called progress. Or what we call progress.
People were moving to the city at an alarming rate. Industrialization was in full swing. Mechanization of agriculture to feed the people in the city was at a fever pitch. Supermarkets were only an improved way to market, promote, and offer the commodities to an ever selective (and demanding) public.
With the mechanization of grain production, and a large percentage of the population that did not raise their own food, chicken became a more and more lucrative market. Because of their growth rate, and the scale they could be reproduced, an emphasis on the production of poultry grew.
Quickly the old breeds were left behind for the more modern breeds, because economically they made more sense. The concerns were practical. They did not have the luxury of a love affair with nostalgia like we do today. These were not emotional decisions. The city folk did not care what breed produced those eggs or carcass. It was about a product, cost, and profit.
The breed that you have is a very commercial breed. It was in it's time, and usurped the competitors that came before it. For a time if it was not a NH, it was crossed with it. It was a quickly changing and evolving time. The breed came on fast, took over fast, and were left behind just as fast.
We do better to understand this time period concerning our hobby when we leave our emotions out of it. We tend to want to insert more than what was there. The majority of people then only cared about product and profit. If it was better, it was. If it was not, then it was not. The people then embraced progress. Progress put food on the table. Literally. Only today with our bellies full are we as inclined to get emotional about our food.
I am a bit nostalgic myself. I am not enthralled by this progress either. It does not care whether or not I am though. It will continue, and at some point there will be a correction. There is always a correction. The best that I can do is carve my little humble existence out as I am, until I am not.
