I will never go to a zoo. I understand that we may need to breed captive animals that are threatened, injured or on the brink of extinction, but animals on display for entertainment, not for me, thanks. Even my cat is free-range.

Cage eggs are becoming a thing of the past on the whole, though a third of our eggs still come from hens in "enriched cages," which are bigger (but still awful) than the pre-2012 battery cages, now banned. Barn eggs are common still, and from what I've seen around here "free-range" is a concept that needs a serious rethink. I know one place that has huge barns with pop-holes and I never see the hens in their outside enclosure. Their eggs are still sold as free-range. In farming, the concept of "what the eye doesn't see" is heavily guarded.

Tell us about your US chickens. We don't want them here...
