The house next door to our friend in Boston had hens in a cage. It was a residential area, I thought it interesting they could do that (Newton, MA).
When I stayed at my grandparents as a kid, I'd go out in the morning to get eggs to be cooked. I didn't think they tasted any different from grocery store eggs.
The wife likes fish eggs a lot. They are really expensive. That is something I don't get really. Escargot, fine with me, but caviar? Meh.
