We keep six chooks. Most of my life I've kept a few chooks. My Nan always had hens as well. Even in the city I've found its ok to keep them. On our street several families have a few hens.
They are really easy and entertaining. I always have beautiful healthy yellow eggs that make most shop ones look depressed and insipid! I can always whip up a quiche or cake, lemon butter... or give someone half a dozen eggs and some herbs as a little gift.
Chooks have personalities and are really friendly. They bring a little joy to everyday.
