You can't easily raise them for meat at scale like you can hens. Roosters are highly territorial and noisy. Nobody wants a chicken farm next door, but they sure as hell don't want a chicken farm with 100,000 roosters crowing and fighting with each other all day long.
Yes but the hens brought into this world and raised for meat or egglaying are eventually slaughtered. That's why they come into existence: because we want them to for that purpose.
The rate and quantity of the slaughter is pretty much 1:1 with the rate at which male chicks are disposed of. How is there any moral difference between expediently terminating male chicks, and taking 48 days before doing the same to hens?

That's humans' intentions not why they come into existense. Just like you and I did not come into the world simply because our parents decided to, animals also are born not because of but despite human intentions.
I was merely replying to that one statement. Morally, I am on the fence on this, but it might be better to let them loose into the wild where they can feed predators amd contribute to an ecosystem. For example wolves kill and endanger animals so they're hunted but chicken are easy to catch and feed upon. You still have to discard their dead bodies so whh not discard them live into the wild.
The output isn't wasted, it's where the chicken in cat food comes from.
