No, but it was an appeal to authority.

Bold of you to assume I consider PETA to be an authority on anything. I was making the point that the same dumb ass group that protests Mario games has publicly supported a method of killing animals.

What do you do with boy chicks after hatching?

take care of its nutritional and medical needs, then kill it as quickly and painlessly as you can with what's available.

Why would their age change anything?

Can you point me to one farm where I could get chicken meat from where all chickens are taken care in the way you've described,

Yeah, but I'm not comfortable telling you what farmers and farmers markets live near me, or telling you what area I live in. It's much cheaper for Tyson to buy chickens other people have spent money raising, instead of paying for their care themselves.

So it is not painless altogether, correct?

I don't know how painless it is, I've never been euthanized before. But I'm not about to call a vet a callous, cruel murderer when they put a dog down, am I? That's why I said as painless as possible. I'd say the same about euthanizing a human.

When I say cruelty I mean an act of inflicting pain (psychical and psychological) to another sentient being without holding an intent of helping that being (think medical procedure, for example).

Oh, so you don't mean cruelty. Because cruelty requires indifference towards suffering even if you didn't inflict it. Torture involves inflicting severe pain or suffering yourself.

Even if I used cruel in that sense, should we inflict avoidable pain on others

Sure, if that's what they're into.

only because they might feel pain for other reasons?

Since when was avoidable pain inherently bad?
