I think vegans care more about the fact that chickens are kept to produce eggs than anything. On the other hand, there are also many vegans who aren’t ethically vegan, but rather are vegan as a result of an Avoidant Restrictive Food Intake Disorder caused by knowing how the sausage and eggs are made and being completely horrified by the idea in the same way many wouldn’t want to eat an eyeball or various other parts of an animal.
