Being eventually eaten by a predator is fairly probable part of any birds life.

So you prefer to deny this chicken the chance to live any life because you can't make it perfect?

You want to distance yourself so far from cruelty that you don't want to let anything live until you are able to provide better conditions than any mythical god could? ;-)

Around me, I see plenty of free-roaming chickens. The big problem is raccoons, you just need to make sure the chickens are put up at night and they usually make it.

This level of purity regarding cruelty avoidance seems to have logical gaps, e.g. what about the suffering of eagles? (Or other predators)
