I had chickens for around 10 years, I think we started with about 20 hens and a couple roosters. It was fun at first, then just fine, but eventually the kids and I slowed our egg intake and they just became more work than fun. 20 hens in their prime lay a lot of eggs, so even though the kids and I were eating 4+ dozen eggs a week, I was constantly giving them away. Then as the number of birds fell (dog, bird flu, whatever) and they got older, by the time we were down to 6 birds, the juice just wasn't worth the squeeze. Which means I can't imagine any scenario short of nuclear war where I would want to have 4 chickens.
I do miss having them to toss table scraps to. Always amused me as they fought over noodles, old bread, whatever.
