I believe the cooking changes happened, but I don't believe the authors conclusions as to why the changes happened. For instance, it was common place just 25 years ago that the Thanksgiving turkey was slow cooked for like 12 hours and basted while it sat in a pan, or kept and cooked inside an oven bag. More recent times, word has spread that it ends up way better to cook it faster at a higher heat. Not because anything about the birds changed, but because we became more educated at cooking and taking temps and different methods were able to be tried and shared faster due to the internet existing.
I'm betting chicken always could have cooked faster. I'm also betting something else is the reason for the custard recipe besides yolks binding less. Eggs changed a lot over the mass production thing, but nothing has reported a change or drop in the proteins. There's also a 100 ways to make an egg custard so chances are more that the older recipe had several differences compared to the newer one. I'm sure more modern egg custard recipes are different again. A lot of the popular ones today don't just use the yolks and don't even use whole milk. Cooking methods always change.

Chicken can be cooked to temperature quickly, but that alone likely wasn't enough. We know this for plenty of cuts of pork and beef that the connective tissue needs time to break down, not just a pure cook to temperature (see braising, smoking, and sous vide techniques).
Something like coq au vin, which was developed for cooking older, tougher roosters, traditionally calls for a low and slow cook to break down the tougher animal.
You can also see the difference when buying cuts like vaca vieja (old dairy cattle slaughtered for meat), which calls for different preparation based on the tougher meat.
So no, I can believe the meat itself is very different today, and the recipes adjusted to the change in ingredient characteristics. We've documented that the manner of raising animals is totally different, so why would you be skeptical that the meat is different?
You're comparing animals with fat throughout the muscle to birds that don't. Also, the connective tissue only starts to break down once getting to about 192f and needs to hang out for a good while between there and 210 to slowly break down. That's not how your great great grandma cooked chicken. Also, steak was best 200 years ago as it is now. Cooked really fast with some red in the middle.

No, I'm comparing the same species of animal. We've gone from 100+ day old birds weighing 2.5 lbs to 47 day old birds weighing 6.5 lbs in the last century. That seems comparable to the difference between old roosters for coq au vin or old dairy cattle for vaca vieja and their respective supermarket counterparts.

No, collagen starts to break down slowly as low as 130°F, but the breakdown speeds up as the temperature rises. There are ways to play around with this with different techniques, where doneness is more than just getting the meat to temperature. It's why poaching chicken used to be more common than it is today. It's why chicken wings taste best when double fried. It's why confit works so well for duck legs.
Also, steak was best 200 years ago as it is now.
Ok, again, if you've ever had to work through cooking something like vaca vieja, you'll notice that it doesn't cook the same way as a steak that's been dry aged, or a regular steak at Costco, or a lean grass-fed steak. If your steak technique is the exact same for all of them, you're probably missing out.
And I'm guessing the NY Times wasn't exactly building this conclusion based on only steak recipes. 150 years is gonna have a lot of non-steak recipes in the mix.
Methods changed because we got better at cooking.
That's part of it. But also, trends come and go. I'd rather have a 1950s cheeseburger than a 1990s cheeseburger, and much of the post 2010 scene has been re-implementing some old techniques that fell out of favor (smashing patties, simpler bread for buns, fewer toppings) and a backlash at some of those things that got out of control. Cocktails went through something similar too, with old classics coming back (either as is or with a new variation).
I'm sure any comprehensive catalog of recipes over decades is going to include some fads that fizzled out, like low fat stuff in the 90's, etc. It's not some kind of inexorable march of progress.

A few months ago my mother bought a free range chicken for lunch. It took over twice the ordinary time needed for cooking a chicken. The difference was massive and obvious, no way is there an another explanation.
They just used to overcook chicken.
Do you look at the old pictures (photos, paintings) of food and see overcooked chicken?
Burning the outside is visible. Over cooking meat definitely is not visible, unless you way, way, over cook it. A pork loin cooked to 145f can look almost exactly like one cooked to 170f from the outside.
Age and activity level absolutely effect how "tough" meat is. I've raised and cooked both heritage breed chickens and modern broilers. The former take 2-3 times as long to reach maturity, are far more active, and as a result are "tougher". You can cook them just as fast a broiler, but the end result is going to be tough/chewy meat. The longer cooking time is needed to achieve equally tender meat.
It's the difference between cooking a rib-eye and a brisket.
The point the article is making is that it's not just a matter of us having different ways of cooking for these recipes... it's that the old recipes simply don't work because of the differences in our ingredients now. Just because one can cook a custard differently isn't the point: it's that the old recipes simply don't work now because the egg is different. Likewise follow the same chicken recipe and it calls for cooking 45 minutes and now we realize the chicken is done and tender in 20... this ain't your great-grandmothers chicken.
I'd argue the chicken is because we have a better grasp of safe cooking temps. The chicken didn't used to take longer. They just used to overcook chicken.
About 150 years ago they threw a doctor in an insane asylum for suggesting to wash hands between patients and until fairly recently no one used meat thermometers. So yes. They didn't have a bead on it 100 years ago.
You don't need a thermometer to cook chicken.
You cook it and taste it.
Was it raw? Was it tough? You cook it slightly longer or shorter next time.
People didn't have microscopes hundreds of years ago, but they were as intelligent as we are.
And you don't need to understand germ theory to know what tastes good.
The fact that you're even entertaining this is ridiculous, and I refuse to engage further.
