I don't raise meat birds. I know *I* could never process any of my birds because I've made them my pets. I was involved in assisting my grandmother when I was very young as she prepared two hens for food. I found it interesting (even though my parents did not want me observe, much less help out). Granny grabbed each hen individually, twisted it around in the air, then chopped its head off. She dunked the bodies in scalding water and I plucked them after she showed me how to do it. She didn't name any of her chickens, except the rooster, who apparently lived a much longer life than any of the hens. Until they were selected for eating, they were kept very well, humanely, and possibly even spoiled to some extent.
The only creepy bit were the two disembodied heads, which clucked silently for a few minutes. My father explained why there was no sound coming from the beaks. I believe I was about 7 years old at the time.
Nearly fifty years later I am quivering in anger at what you've reported happens to you. How {expletive deleted} rude of those people! What business is it of theirs, anyway? Some of them are your family members? Oh, aren't relatives such pains in the behind, sometimes?
As for anybody not related to you (which you have no control over), there should be something pithy and pointed to say to them. Something along the line of "I prefer my food fresh, chemical free, and while they're growing I treat these chickens much better than any you have ever eaten, anywhere."
And they can go bugger themselves, exactly as someone else has already said.
