It’s perfectly easy to keep chickens in the city, as this video in the Guardian shows. As well as providing a fresh supply of free range eggs, they also make nice pets for children and eventually, when their laying capacity drops, dinner. The family in the video, who live in East London, invested in an Eglu, a highly practical plastic hen house, designed for easy cleaning and egg collecting. After this initial outlay, keeping chickens is a low-cost activity, as their diet can be augmented by scraps like stale bread and apple cores. If you let them forage in the garden, they’ll also eat slugs.
But there’s one thing to watch out for: now that foxes have moved to town, the chickens should be well cooped up at night.
