i only want to eat happy animals, is that wrong?

in the past, i have grappled with vegetarianism and have pondered, recently thanks to my newly converted vegetarian daughter, the idea of 'eating dead animals'. i grew up eating meat, in fact, it was not a 'meal' according to my father if there was no meat. now as an adult, and with the responsibility of feeding my children, we have chosen to go the natural, organic, no pesticides/hormones and no antibotics route. partly this is for health reasons - our son had several 'super bugs' in the NICU and we were advised that we should avoid any thing that would further jeopardize his immune system. while i do not feel 'guilty' for eating meat, i do want the animals to be treated well and slaughtered humanely. this is very important to me. i want the cows and chickens to be able to enjoy the fields and range free and i want the end of their life to be as pain free as possible. is this too much to ask?
