Great article. Also pretty sad to see what we've ended up with in the name of business. Maybe if humanity survived another few hundred years we will look back on this time of corporations with disgust.
'As a paper in the journal Poultry Science puts it, if humans grew as fast as broilers, “a 6.6 lbs. newborn baby would weigh 660 lbs. after 2 months.”'
So percentage weight isn't a perfect stat for cross species comparisons I understand that but holy shit that's messed up. And it's not like theres no other evidence of this being insanely unhealthy for the species..
In the 1950s, a competition was held to create the "chicken of tomorrow" through selective breeding. This is the path that got us to the modern broiler chicken. Unlike their recent ancestors (and much unlike their distant ones) these birds grow so large so quickly that they are prone to health issues and disease.
I'm all for selectively breeding crops. It's selectively breeding animals where it gets ethically murky for me.
Should we be supporting the breeding of snub-nosed dog breeds, for instance, considering the respiratory issues they have? What about broiler chickens that can't stand up and are prone to cardiac issues? What about egg-laying hens that commonly develop osteoporosis, egg yolk peritonitis, and cloacal prolapse? Cows bred to produce so much milk they display severe discomfort and are prone to mastitis?
Like I said, the lines get blurred quite a bit when you have to also consider the health and comfort of animals.
I'm pretty sure that's a really the same chicken 3 times. I've raised quite a few chickens and grew up around neighbors raising them, though the grayscale makes it hard to be sure.
As someone else pointed out: the comb (head piece) is missing from the first 2 pictures:
Pic 1 looks like a chicken at maybe a month old or so, maybe a bit younger?
Regardless of whether they used the same chicken for the photoshoot, these images pretty accurately depict how drastically broiler chickens have changed through the latter half of the 20th century.
Prior to the 1940s, chicken wasn't a super popular meat, and it was generally old egg-layers that were killed for meat. As demand for chicken grew, broilers were selectively bred for feed conversion, weight and time to slaughter.
The modern broiler chicken grows to an enormous size in a very short (6-8 week) timeframe. They also tend have some pretty bad health issues as a result: impaired mobility, cardiac issues and a compromised immune system.
If all adult chickens had to live with the "1957" version which I understand to only be a young chicken, then I think we'd be screwed. Remember these things are the descendants of dinosaurs. A rooster that lean, in it's adult stage, would likely fuck you up more than a jackrabbit with the untrimmed nails of a lop-ear. And be almost as agile in avoiding your retaliations. Like geese and fast zombies shacked up.
Birds are basically today’s lizards and like most lizards can live a very long time and grow throughout their lives. When you think about how big alligators can get in a similar amount of time, it isn’t surprising that chickens can also.
I have a 23-year-old ball python. I can confidently say he has not grown throughout his entire life, and has in fact for the last almost two decades stayed at a comfortable 3.5’ long.
