I have some friends who keep chickens for eggs. They are not fertilized and one friend and her husband keep the chickens as pets. They (da chickens) just kind of roam all over the garden gobbling up little bugs and stuff. Believe me, these people are not vegetarians, but they are very conscious of humane care of animals.
As I've gotten older, my resolve to not eat any animal products has only strengthened, especially given the crap that some very juvenile posters on this forum throw at those of us who don't eat animals. Doesn't sway me one bit...in fact I've probably done more research on where commercial food comes from and what's in it since I started posting on this board. I know more about the diets of people who chow down on fast food crap than they do.
As I've said a bazillion times, to each his own. I choose not to eat any animal products, not flesh, skin or fur. This somewhat limits good clothing and shoes that aren't horrendously expensive (because it's made by hand). So, the only thing that suffers is my incredibly out-of-date wardrobe ~
Ultimately, you are the only one who has to live with your decisions and conscience. You must make decisions that you are comfortable with. Again, to each his own.
