Chicken Coops and Housing: What You Need

Before you bring any birds home, the single biggest decision you'll make is the coop and run. Get this right and chicken-keeping is genuinely easy; get it wrong and you'll spend the next two years fighting damp, mites, bullying and — worst of all — foxes. Everything else, from feed to breeds, is secondary to giving your hens a dry, secure, easy-to-clean home.

This guide walks through exactly what a coop needs, the wood-versus-plastic question, how big the run should be, and how to make the whole thing fox-proof. If you're brand new to all this, start with our beginner chicken guide for the bigger picture, then come back here to sort the housing.

What a coop actually needs

A hen house has one job: keep your birds dry, secure and comfortable overnight. It doesn't need to be pretty or elaborate. It needs four things done properly.

Perch space. Chickens roost off the ground at night — it's an instinct that keeps them away from predators and damp. Allow roughly 20–25cm of perch length per bird, using a smooth bar (a rounded length of 5cm timber is ideal — round dowel is too thin and harder for them to grip). Perches should be higher than the nest boxes, or your hens will sleep in the boxes and foul the eggs. If you have more than one perch, keep them level; birds will squabble over the highest spot.

Nest boxes. Hens like a dark, private corner to lay in. You need roughly one nest box per three to four hens — they happily share, and you'll often find them queuing for the same favourite box anyway. Each box wants to be about 30cm square, with a lip to keep eggs and bedding from rolling out. Site the boxes in the darkest, lowest part of the coop, away from the perches.

Ventilation without draughts. This is the detail most beginners miss. Chickens give off a lot of moisture overnight, and damp — not cold — is what causes respiratory problems and frostbitten combs in a UK winter. You want vents up high, above the birds' heads when they're roosting, so stale air escapes without a cold draught blowing across them. A coop sealed up tight is far worse than a slightly breezy one.

Easy access for cleaning. You will be cleaning this thing every week for years, so don't underestimate it. Look for a coop with a removable droppings tray under the perches, a roof or large side panel that lifts or hinges open, and nest boxes you can reach from outside (an external "egg port" with a lift-up lid is a lovely thing). If you can't get your arm and a scraper into every corner easily, you'll skip the job and the birds will pay for it.

Wood vs plastic coops

The classic wooden coop looks the part and is usually cheaper to buy, but it has one real enemy: red mite. These tiny blood-sucking parasites live in the cracks and joints of the timber — not on the birds — and emerge at night to feed. They breed explosively in warm weather and a bad infestation can make hens stop laying, go off their food, or in severe cases die from anaemia. Wooden coops give red mite hundreds of crevices to hide in, which makes them very hard to clear once established.

Plastic coops (the moulded kind) changed the maths here. Because they're smooth, with far fewer joints, red mite have almost nowhere to hide, and you can blast the whole thing clean with a hose or pressure washer and let it dry in an afternoon. They cost more upfront and divide opinion on looks, but for a first-time keeper the easy cleaning and mite resistance are a genuine advantage. For more on spotting and treating an infestation, see our guide to keeping chickens healthy.

If you do go wooden — and plenty of people happily do — treat it with a poultry-safe preservative, check the perch ends and joints weekly in summer, and keep a tub of diatomaceous earth or a proper mite powder to hand. Whichever material you choose, a coop you can take apart and clean quickly is worth more than one that merely looks good in the garden.

Run size: the daily run vs free-ranging

Your hens need space to scratch, dust-bathe and potter about, and how much they get is the difference between calm, healthy birds and bored, feather-pecking ones. Crowding is behind a huge share of the problems beginners run into.

As a working minimum, allow at least 1 square metre of run per bird, and treat that as a floor, not a target — more is always better. A pair of hybrids in a tiny ark-style run will quickly turn it to bare mud; the same birds in a generous run, or with daily time to range, stay far happier.

There are two ways to give them space:

• A permanent attached run. The coop sits inside or alongside a secure mesh run the birds use all day. This is the safest setup — they're protected even when you're out or away — but the ground inside takes a hammering, so site it where you don't mind losing the grass, and consider hardwood chip or a moveable run to spread the wear.
• Free-ranging. Letting hens roam the garden (or part of it) for a few hours a day gives them the best life and the richest eggs, but they're exposed to foxes the whole time and they'll happily demolish your veg patch. If you grow your own, read how chickens fit alongside your vegetable garden before you let them loose near the seedlings.

Most keepers do a bit of both: a secure run as the default, with supervised free-ranging in the evenings when you're around to keep half an eye out.

Fox-proofing: the predator that matters

In the UK, the fox is by far the main predator of garden chickens — in towns as much as in the countryside. A fox will return night after night, can dig, climb and squeeze through surprisingly small gaps, and will kill every bird it can reach in one visit, not just the one it eats. Assume one is testing your defences right now, because it probably is.

Fox-proofing comes down to three things:

Sturdy mesh, not netting. The flimsy green plastic or chicken-wire netting sold for runs will not stop a determined fox — it can tear or bite through it. Use galvanised weld-mesh (welded steel grid) for the run, with a hole size small enough that a fox can't push its muzzle through. The whole structure needs a solid frame, too; foxes will lean on and lift weak panels.

Stop them digging in. Foxes dig under fences. Either bury the mesh 30cm down at the perimeter, or — much easier — lay a horizontal "skirt" of weld-mesh flat on the ground extending about 30cm outwards from the base, pegged down and grassed over. When the fox tries to dig at the edge, it hits mesh and gives up.

Lock up at dusk, every single night. The coop itself must shut tight, with a bolt a fox can't nose open (the swivel "fox-proof" catches exist for a reason). The danger window is dusk and dawn, so the pop-hole needs closing at nightfall and not opening until morning. The catch is that this means being home at dusk 365 days a year — which is where an automatic pop-hole door earns its keep. These run on a timer or light sensor and close the hatch at nightfall, so a late evening out no longer means a dead flock. For most keepers it's the single best upgrade you can make.

Bedding and where to site the coop

Inside the coop you need bedding in two places: a deeper, soft layer in the nest boxes for the eggs to land on, and a thinner layer on the floor and droppings tray to soak up mess. Good choices in the UK are dust-extracted wood shavings or chopped hemp or straw bedding — all widely sold for poultry. Avoid sawdust (too fine and dusty for their airways) and avoid hay, which goes mouldy fast. For the nest boxes specifically, soft straw or shavings work well and are cheap to refresh.

Siting matters more than people expect:

• Pick a sheltered, well-drained spot. Hens cope with cold far better than damp. Avoid a frost pocket at the bottom of the garden or anywhere that puddles after rain.
• A little shade is good. Chickens suffer more in heat than cold, so some afternoon shade — a tree, a fence, a corner of the house — helps in a hot spell.
• Not too far from the house. You'll be out there twice a day in all weathers. A coop a long, muddy trek away tends to get neglected on dark January mornings.
• Think about runoff and neighbours. Don't site it right against a fence line if smell or noise might be an issue, and make sure droppings won't wash into a pond or watercourse.

A simple cleaning routine

Keeping a coop clean is the main thing that keeps your birds healthy, and it needn't take long if you stay on top of it. Build a rhythm rather than waiting for it to get bad.

Daily (two minutes): scrape or tip the droppings tray, top up food and water, and collect the eggs. Quickly check the birds look bright and are moving normally.

Weekly (fifteen minutes): remove and replace the soiled bedding, scrape the perches and tray properly, and refresh the nest-box bedding. In summer, this is your moment to check the perch ends and joints for red mite while you've got everything out.

Monthly to seasonally: a full strip-down and proper clean — every surface scrubbed, then a poultry-safe disinfectant, and the whole coop left to dry before fresh bedding goes back. This is where a plastic coop you can hose down saves real time. Compost the soiled bedding and droppings; well-rotted, it's excellent for the vegetable garden — just don't put fresh droppings straight onto growing crops.

Get into this routine and red mite, smells and disease rarely get a foothold. A clean, dry coop is the foundation of the whole thing.

What you'll need

Once you've understood what makes a good setup — secure, dry, easy to clean, fox-proof — these are the pieces most UK keepers end up buying. There's no need to spend a fortune; spend it where it counts, on security and ease of cleaning.
