We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
That was an old obit from 2003. He was an impressive man.
It is true that chicken and turkey were once 'special occasion' meats. Their industries have done an impressive job expanding their market share.
Chickens convert grain to meat much more efficiently than cattle or hogs and the bird's short lives are an added advantage that makes them the cheapest meat to produce.
The poultry industry is so efficient that you can buy fresh chicken in the market for less money than it would cost to raise them your self.
It needs to be said low cost factory farmed poultry could never have happened without antibiotics. I would argue this was more important than the genetics because there is no way you could keep thousands of birds alive under one roof without them.
While I am thinking that being the lowest priced product in the meat case is the primary reason for chicken's success, they have also benefited from 40 years of bad press for the beef industry.
