My dad told us stories of when he visited his cousins on the farm and they as little boys would have to go out and chop off a chicken head so they could have dinner. It has been happening since the beginning of time. I think it is how you prepare your kids for it, it is ALL in the RESPECT. We do this for our food, they are here for our food and use, but we treat them humanly.... We thank them for their life.....I think if they want to see then let them see but leave at any time.
