I’ll provide a few examples…. unfortunately…. worldwide as well as in the U.S.
PETA has a reputation for unreliable reporting, so I generally do not use them as a source.
However, the articles you linked are all discussing things I was aware of from other sources that I trust more (so yes, I DID know about all of this).
That one's about chicks that die in shipping, and wanders into problems with factory farming in general.
No amount of "hatch to order" by hatcheries will fix problems with the Postal Service.
Every chick that died in shipping was hatched, boxed, and sent to someone who DID order it, did want it, and did have proper facilities to care for it.
Also, that was news only because it was unusual. It is NOT the normal thing with shipped chicks.
The bad conditions of animals in cages, and debeaking, have nothing to do with whether chicks were ordered before they were hatched. That is what happens to the birds that ARE wanted. Yes, it's a problem, but not one caused by the way hatcheries operate.
That is mostly about male chicks of laying breeds.
Again, no amount of "hatch to order" will fix that, until someone can find a practical way to determine gender of chicks before they develop in the eggs, or find someone willing to order male chicks.
It also mentions chicks hatched with deformities-- that is something that happens on occasion, for any species (including humans.) Large commercial breeders try very hard to breed chickens with no deformities, because they want healthy chickens suitable for laying eggs, or producing meat, or whatever purpose they intend those chicks to serve. (Small breeders also try to breed for chickens with no deformities, but it looks like you're more concerned with the large ones.)
As regards the workers treating chicks roughly: I agree that is a problem, but it has nothing to do with whether orders should be placed before chicks are hatched. It could be fixed by a combination of proper training of workers, proper supervision of workers, and hiring enough workers that they do not have to rush.

Yes, late-hatching chicks, weak chicks, and chicks with deformitites are a problem.
And what to do with them is a good question.
But hatch-to-order would not help in any way: these chicks would still be a problem.
I know of at least one hatchery that DOES sell late-hatched chicks as a special deal, packed up at the end of the day when it's too late for them to go in other orders:

Weak chicks and deformed chicks will always happen, if chicks are hatched at all. If someone tries to raise them with normal chicks, they will suffer, and die slowly. (I think a quick, painless death is the kindest thing that can be done for them. The only question is how best to provide it.)
The part about "never experiencing their mothers’ nurturing or warmth" is just stupid. Chicks in an incubator are already warm. And a hen will often KILL chicks that hatch late or deformed. Or she will walk away with the healthy chicks, leaving the late ones to die of exposure. (Not always, but quite often enough to make PETA sound stupid for saying it.)
I’m a vegetarian actually, so that was part of my interest when I was asked by a professor to do some research on the subject of factory farming and similar issues.
Are we discussing hatcheries that sell chicks to the public?
Or ones that hatch large numbers of chicks for factory farming?
Because the ones for factory farming DO have a contract for a certain number of chicks, before they ever put the eggs in the incubator. They would be the BEST examples of what you say should happen, but they are the ones primarily being criticized in the sources you linked.
(Yes, I agree that there are problems with the current factory farming system. But since this thread started as a discussion of hatcheries, the other factory-farming points are very much off-topic.)
