Counterpoint, while cook time might not make a direct profit like fatterfaster-growing chickens do, it would probably still make the chicken more desirable due to the decreased cook time; especially if you could advertise it as a feature.
"Life's fast, so why isn't cooking faster? Are you tired of your chicken taking hours to cook? Buy Bryson's Chicken Breasts!
"Bigger!
"Fatter!
"Healthier!
"and faster!
"Our chicken breasts are designed, formulated and engineered to be as big, nutritious and delicious as possible; while also being faster and easier to cook than other brands. So why spend hours cooking normal chicken breasts, when you could cook Bryson's Chicken Breasts in a fraction of the time? Buy Bryson's; you won't regret it."
Edit: misread "faster" as "fatter" lmao. Point still stands though.
It might, but you would need to track down a heritage breed. Modern chickens have been selected to grow big and fast. They also lay eggs FAR faster. This, unfortunately, lowers the quality of individual eggs. Poor diet and conditions reduce this further. Home raised chickens fix the diet and conditions, but still use fast laying breeds.
Alternatively, duck eggs tend to be a LOT better. They have not been as heavily selected for laying speed. They also, naturally, have a more intense yoke. I grew up in a pub, in my youth. It took a while, but the customers eventually made the connection between our unusually tastes pies and pastries, and the pair of ducks living in the gardens.
Not a sign of the times, a sign of the raising. I've eaten Perdue and I've eaten small farm, free-ranging chickens. The latter is often leaner, tougher and incomparably more flavorful.
It depends of how they are raised. Here in France, we have a "Label Rouge" sign : https://en.m.wikipedia.org/wiki/Label_Rouge . Label rouge chickens are like twice the price or more, but they are flavorful compared to the cheapest ones. There are other great labels (Loué, Janzé, bio, Nouvelle agriculture, ...).
I think it's just that white folks' tastes have become more accustomed to stronger seasoning. Mine certainly have since I was a kid in the 1960s. Of course some of that is just age progression for an individual, but it's mostly cultural mixing. And following the Penzeys advice to "Season Liberally."
All animal products that come from factory farms taste different than properly raised animals. Industrial beef smells like corn and tastes bland compared to well cared for beef, but you will pay a premium and it can be hard to find the further you are from the country.
If you haven't had deer, elk, or bison, you need to so you can taste what red meat is suppose to be and you can feel better knowing that the animal lived a great life in the wild before it was murdered.
Fruits and veggies are the same way. Large farms grow plants to look good and keep looking good long enough to travel around the world twice and sit on a store shelf. Small local farmed plants are more likely to actually have flavor, at the expense of not being perfectly round and shiny (and spoiling ten times faster).
That has a part in it for sure, but chickens raised on small farms are handled way better too. Better fed, better rested, better exercised. I'd have trouble believing that doesn't have any impact on the final result.
Regarding eggs... Somehow it seems that eggs have gone rather small. When I have to buy eggs in the supermarket, they often have only S and M sizes, and they are usually at the lower end of the weight group. I have checked, M oficially range from 53 to 63 grams here, but I've tested several egg cartons I've bought at supermarkets here and had only one egg of 60g in a total of 80, everything else was usually in the 51(!) to 58g range. In comparison to the XL eggs I usually buy at the local farm shop, this is quite a difference.
Interesting that egg sizing labels aren't that universal. In the U.S. most big stores primarily stock Large (minimum weight 56.7g) and Extra Large (63.8g), while Jumbo (70.9g) is still probably more common than Medium (49.6g).
(My methodology for getting weights was that I used the government labeling requirements for minimum weight per dozen, converted ounces to grams, divided by 12).
Our ranges are S for anything below 53g, M to just below 63g, L to just below 73g, and XL for anything 73g and up. I had eggs in the 85+g range from that farm shop occasionally (that must have been a monster chicken!), and even one 10-pack with 7 double yolk eggs once.
Once they had an offer of size S eggs, and even small ones for that group. They were not much bigger than Quail eggs and from the first layings of young hens. I bought a box of them for fun and fried three of them for breakfast. My son took a look at the tiny little egglet I placed on his plate and he asked me what I had done to the rest of the egg...
btw that cookbook is incredible. I have the most recent edition and it has so much information and such a deep well of amazing cooks. Highly recommend!
