Sure!
First off, it's not that these animals would live otherwise. They can't survive in the wild, the only reason they exist at all at this scale is because there is an economic incentive to keep them - namely, meat, eggs, milk etc. Would you rather have them live a short live or not even be born because their parents died in the wild?
Second, perfect is the enemy of the good. Most people won't stop eating meat no matter what you tell them, so, regardless of your stance, a push for more ethical farming is beneficial.
