Is it still anecdotal if literally any farmer will tell you the same? Because they will.
A surprisingly large amount of effort goes into trying to keep the livestock from hurting themselves or getting themselves killed. That's inevitable when essentially turn off natural selection, they end up losing any sense of self preservation. And why not, they do have multiple humans who's entire career centers on keeping them alive until they're ready for slaughter.

They live more comfortably than you do. In an environment literally designed to maximize their ability to grow.
Y'all continually fail to understand that farmers have a direct financial incentive to keep these animals happy and healthy. Stressed animals don't grow nearly as well as happy animals, and small animals don't make money.
Taking proper care of the animals is more profitable in the long run, even if you assume that all farmers are heartless monsters who enjoy watching needless suffering (we aren't by the way).
They live more comfortably than you do. Food and water freely available, plenty of space, other animals to socialize. No worries or responsibilities, not even a real concept of the outside world. The farm is all they've ever known, and it's all they ever need to know.
They are hearty for sure and that can be seen as an urge or will to live. Animals are dumb and have a shocking lack of self preservation. Are you talking about conscious 'I want to live, I better not do that' or 'I will find a way to live in my circumstances'?
So did the animals in the ecosystem that go wiped out to make factory farms that make fruits, vegetables, coffee, etc. There’s no innocent way to feed oneself in a factory goods based society. Only slightly less guilty ways.
