Three hens, a timber coop and a corner of lawn that never quite recovers: that is how a lot of British gardens begin their life as a very small smallholding. Keeping a few hens is one of the most rewarding things you can do with a patch of outdoor space, and it is far less complicated than the internet sometimes suggests. The difference between a happy flock and a daily chore usually comes down to the preparation, not the hens.
Before you fall for a particular breed or reserve a trio from a local supplier, work through the questions below. None of them are difficult. They just need answering in the right order.
Space: think run, not garden
The size of your garden matters far less than the size of the area the hens will actually use. A widely used rule of thumb for a small back-garden flock is at least one square metre of run space per hen, and considerably more if they will be shut in for long stretches. Three hens in a run the size of a dining table will look cramped and turn the ground to mud within a fortnight. Three hens in something twice that size will look busy and settled.
Inside the coop, allow roughly 25cm of perch per bird and one nest box for every three or four hens. Hens are social animals, so two is a poor number — they do better in a small group of three or four.
Be honest about the lawn, too. Any grass the hens can reach will eventually be scratched bare, especially around the coop door. Plan for a covered run, a movable ark, or a hard-wearing surface such as woodchip. Tidy, well-drained ground is easier to keep clean and kinder on their feet.
Choosing a coop that will last
Ventilation above the birds' heads, no draughts at their level, and a door you can open one-handed while carrying a bucket. Those three details matter more than the paint colour.
Look for a coop that is raised off the ground, has a solid floor, and includes a sliding or hinged pop hole with proper bolts rather than simple hooks — foxes are remarkably good with hooks. Check the roof overhangs enough to keep rain off the run entrance. And measure before you buy: the smallest coops on the market are sold on appearance, not on what a hen actually needs.
Plastic coops are easier to hose out and less welcoming to red mite, the tiny parasite that makes hens anaemic and keepers miserable. Wooden coops look better in a garden but need checking in every crevice, perch end and joint. Whichever you choose, you should be able to reach every corner of the interior with a scraper.
Foxes, weather and the ground underfoot
Foxes are not a country problem. Urban foxes work gardens at dusk and in the early morning, and a flimsy run will not stop them. Build as though a fox will test it.
- Use welded mesh, not chicken wire, which tears far too easily.
- Bury or skirt the mesh at least 30cm outwards and downwards, or stand the run on paving slabs.
- Cover the top with mesh or a solid roof — foxes climb.
- Check latches weekly; a bolt is better than a twist hook.
- Keep the run clear of clutter so nothing can be used as a step.
Ground management matters just as much. A run that becomes a swamp in November causes foot problems and smells. Woodchip, sharp sand, or a slabbed area around the drinker will keep things manageable, and a covered section gives the hens somewhere dry to dustbathe.
Bedding, cleaning and the daily round
Wood shavings or hemp make good, absorbent bedding for the coop floor; straw is best kept for nest boxes, where hens like to shape a hollow. Avoid anything dusty or mouldy, and never use hay, which goes musty quickly.
A realistic routine looks like this:
- Morning: unlock the pop hole, check the drinker, and look at each bird as it comes out.
- Evening: collect eggs, count the hens back in, and close the pop hole if you have foxes nearby.
- Weekly: turn over the bedding, scrub the drinker, and check perch ends and nest box corners for red mite.
- Monthly: full clean out, fresh bedding, and a walk around the run looking for holes or rust.
Five minutes a day and half an hour at the weekend is genuinely enough for a small flock.
Feed, grit and water
Layers' pellets should be the base of the diet, available through the day in a hanging or treadle feeder that keeps it dry and keeps wild birds out. Offer insoluble grit and crushed oyster shell separately, so the hens can take what they need for digestion and shell quality. Fresh water every day, in a drinker raised off the ground.
On scraps: the old picture of hens living off kitchen leftovers is out of date. Current UK animal by-product rules restrict feeding catering waste, including household kitchen scraps, to poultry. Garden greens, weeds, windfall fruit in moderation, and a small handful of corn as a treat are all fine — but they are extras, not dinner.
Rules, neighbours and paperwork
Check the paperwork before you buy anything. Rented homes, leasehold flats and properties with restrictive covenants may prohibit poultry or outbuildings, and that is worth knowing on day one rather than month six. Small coops usually fall within permitted development, but if you are putting up anything substantial, ask your local planning department.
Registration requirements for poultry have changed in recent years, and avian influenza housing measures can be introduced at short notice, particularly over winter. Check the current position on gov.uk before you order birds, and keep an eye on it if you keep hens long term.
Then there is the neighbour question. Hens are quiet; cockerels are not, and most small gardens should not have one. Position the coop away from shared boundaries, keep the run tidy, and mention your plans to next door before the hens arrive rather than after. If your situation involves a tenancy, a lease or a covenant, take proper advice rather than relying on a forum.
Getting started: your first week
Set everything up before the hens arrive, not after. A sensible order of events:
- Choose and site the coop on level, well-drained ground with morning sun and afternoon shade.
- Fit the perch, nest box, feeder and drinker, and fill the coop with bedding.
- Source your hens from a reputable breeder, a farm supplier, or a rehoming charity if you would like ex-commercial birds.
- Keep new hens inside the coop and covered run for the first few days so they learn where home is.
- Let them out to explore late in the afternoon at first, when they are naturally heading back to roost.
- Find a vet who sees poultry before you need one, and note the number.
Start with three or four hens, give them a season, and see how the space holds up. Arrange cover for holidays in advance — hens cannot be left for a fortnight with a full feeder and hope. Get those basics right and a small flock will quietly become the best part of the garden: the sound of them at the gate, the daily walk down the path with a bowl, and more eggs than you know what to do with by June.
