It's perfectly possible for small farms to raise livestock in the same conditions that you feel are acceptable for your chickens. I and my wife eat meat, but we try to be very careful about where it comes from - small scale local producers or trusted restaurants. But there are always problems when other people prepare your food or it's in a restaurant you don't know.
I find it hard to say to my friends "I'm not going to eat your animal products , but I'm not a vegatarian or vegan." So I just eat what is there and don't complain. I don't get sick either - except from eating products with gluten. I didn't even realize that until my partner gave up gluten and discovered how much it affects me. There is also the issue of eating foods that you haven't eaten in a long time - take almost anything out of your diet for months and you may have problems next time you eat it.
Anyway, most of all you should eat what makes you happy and feel good. If you've found something like that then go for it.
BTW. What discussion on chickens and how they are raised without a reference to this Portlandia "Is the chicken local?" video:
hilarious
