My meat birds live the life. I'm actually keeping two females from my meat chickens so I can breed them in with my flock.As a kid in 4-H it was required to go on the slaughter facility "field day." (cattle)
It was awful! But I learned a lot and I never forgot it. I'm also aware of how typical meat chickens are treated too. Both on the farm and during slaughter.
This is why at my old farm I took my birds to the Mennonites. Of course my birds were always the cleanest ones there and in the biggest and most comfy crates...(large dog kennels) but I knew they would be treated fairly and that was very important to me.
