Many "varieties" of chickens have been bred to grow so large that they cannot stand anymore. Other have been bred to lay so many eggs that their bodies steal calcium from their bones in order to create the eggshells.
Many "varieties" of dairy cows produce so much milk that they endure extreme pain and mastitis when lactating if they aren't taken care of.
Animal agriculture is a endless nightmare. We do need to take care of those animals who have only been born because of humans wanting their bodies and the products thereof. We owe them that much.
Don't worry, vegans. It's perfectly fine if I forcibly inseminate animals, take their babies from them, cut their tails off, confine them in spaces where they can barely turn around, feed them complete garbage, and then give them a haircut with no attempt to avoid cutting their skin with my industrial clippers, because they don't die or anything!!
