There are many different vegans with many different viewpoints. I am not vegan, but I come pretty close - I do still consume a limited amount of dairy, but otherwise I don’t buy animal products. This is for the reasons you say - I don’t want to support factory farming. I also have a limited amount of time in my life for investigating everything I eat, however - I don’t honestly have the stamina to check every egg-containing product to see if it used battery eggs or not. I really don’t have the time to check if the “free range” eggs I’m buying are really free range or if they have sneaked around the regulations and it’s battery farming in disguise. It’s just easier not to buy any eggs.

I will accept eggs from people I know who keep chickens - no problem from me there. I think that humans having relationships with domestic animals is fine, generally we both benefit - the animals because they are protected from predators, they get fed, etc, and us because we gets eggs.

Some vegans would not agree with me. Some vegans don’t believe humans should keep any animals, including pets. I don’t believe there’s an issue with keeping some pets though. Domesticated animals wouldn’t even exist without us… Like it or not their “natural” habitat is living with humans. You couldn’t release all the dogs and expect that to be better for us or them.
