> I think my time spent thinking about other endeavors in my life is more valuable than another 7-17 years of several chickens' life.
I suppose I could argue that you don't even need to spend time thinking about it; you can just stop eating chickens. You aren't faced with a challenge here because the solution is clear and freely available.
> If I believed chickens had a greater sense of sentience, self awareness, and experienced life much at all beyond...
The more I learn about birds the more I think they're far more sentient and aware than we give them credit. Some certainly seem to possess more mental acuity than others, but I no longer believe chickens are vacant little meat vehicles.
One thing to consider is that the chickens you're familiar with have been raised in conditions which are conducive to them appearing fairly stupid. They're trained to expect very regular conditions, and are never given a chance to exercise their brains in order to become sharper or display more awareness.
If you met humans who lived a similarly deprived life, I suspect they would also appear useless and stupid.
We've also bred chickens to be a certain way, and that aspect of it is a bit unsettling to me. If we've in fact created a creature which is that stupid and vacant so we can consume it without feeling bad, there's something disturbing about that picture. It's like removing the soul from something so you can abuse it freely. In order to spare our conscience we effectively had to "kill" an entire lineage of living things. We know that the bird chickens originated from is not a grain-pecking zombie, so... What have we really done, and why? Is that something we should perpetuate? I find it quite a disturbing concept if it were to be true, though I do doubt that chickens truly are so mentally dull that their living or dying is irrelevant.
> I am fine with a chicken living in a servitude that involves walking around in nature, getting fed as much as they want, having shelter and warmth at night, having plenty of social interactions, having human caretakers watching them every day, and getting a quick painless death after a few years.
One interesting thing to me here is: If you think it's okay to kill the chicken eventually, why does it matter if its life prior was good or not? Where do you draw these lines and why? If you care about the chicken a _bit_, why do you, and why don't you _more_? What qualities would a chicken need to possess in order for you to decide it's not okay to eat it?
Upon asking myself this I realized I didn't have good answers. I prefer witnessing chickens being alive over having them on my plate to enjoy for a fleeting moment.
I'm not arguing at all; most people disagree, so I realize I'm probably wrong. It's very much a "feels"-based discussion.
