How To Predator Proof A Chicken Coop And Run

Predators are one of the harsh realities of chicken keeping in the UK. You might never see them, but they are always there. Foxes, rats, badgers and other little blighters can wipe out your flock in a single night if you are not properly prepared. The good news is that with the right setup, you can predator proof a chicken coop and run to create a secure environment that keeps your chickens safe year-round.

Know your enemy: UK chicken predators

Several predators pose a risk to backyard chickens in the UK. The main threats include:

• Foxes – The biggest danger to most flocks. Foxes dig, climb, squeeze through gaps and can even manipulate simple latches.
• Badgers – Strong, heavy and capable of forcing entry into poorly built coops.
• Rats and mice – Primarily target feed, eggs and chicks, but can gnaw through wood and wiring to gain access.
• Weasels, stoats and mink – Agile, fast and capable of entering through very small gaps.
• Birds of prey – Buzzards or sparrowhawks may occasionally take bantams or younger birds.
• Dogs and cats – Domestic pets can sometimes injure or stress chickens if allowed access to the run.

Even city and suburban gardens are not immune. You should always assume predators are present and plan accordingly. I’ve seen a single and very vicious mink wipe out an enrite flock.

Buy a coop that resists attack

The coop is your chickens’ main line of defence, so buying the right one is essential.

Choose secure materials

Avoid flimsy wooden coops sold cheaply online. Many use thin panels and basic fastenings that predators can easily breach. Instead, look for:

• Thick, treated timber
• Strong frame construction
• Well-fitted doors, lids and access points
• Galvanised mesh covering ventilation areas

Plastic coops from brands like Nestera and Omlet have become increasingly popular. They offer excellent predator resistance, being:

• Chew and gnaw resistant
• Smooth-surfaced with few weak points
• Easy to clean and maintain
• Fitted with secure locking mechanisms

In my own setup, I have found the smooth surfaces on plastic coops make it far harder for predators to get any grip or leverage, which adds extra security.

Use predator-proof latches

Latches are often the weakest point of a coop. Basic hook-and-eye catches or slide bolts are no match for a determined fox. Choose coops that feature:

• Lockable barrel bolts or padlocks
• Carabiner clips securing bolt handles
• Integrated locking systems on automatic doors

Check ventilation covers

All ventilation points should be securely covered with galvanised weld mesh to prevent small predators squeezing through.

Reinforce the run properly

Many attacks happen during the day while chickens are out in the run. It needs the same attention to security as the coop itself.

Weld mesh, not chicken wire

Standard chicken wire is not predator-proof. Foxes and dogs can tear through it easily. Use:

• Galvanised welded wire mesh fencing
• 16 or 19 gauge wire
• 25mm maximum hole size

From experience, welder mesh is the single biggest upgrade you can make if you want serious protection that holds up long-term. You can find it here at Amazon.co.uk

Fully enclose the run

The run should be fully enclosed, including the roof. Open-topped runs expose your chickens to climbing predators and birds of prey.

Secure all fixings

Attach mesh to frames using heavy-duty staples or screws with washers. Mesh that is poorly fixed leaves vulnerable points predators can exploit.

Protect against digging

Predators like foxes and badgers will often dig to gain entry. Ground protection is essential.

Three effective methods:

1. Buried mesh skirt – Extend mesh 30 to 45cm underground, bending it outward in an L-shape.
2. Surface mesh apron – Lay mesh flat around the outside of the run, extending 60cm and pegging it securely.
3. Paving slabs – Create a perimeter barrier using heavy paving stones around the run.

What tends to work best in my view is the surface apron method. It is highly effective, requires less digging, and makes later maintenance much easier.

Lock the coop every evening

Always lock your chickens safely inside the coop overnight. Most predators are most active from dusk onwards.

• Use automatic doors if necessary, but check regularly for blockages or faults.
• Keep door tracks clear of bedding and debris to prevent jamming.
• Double check that all doors have closed properly before nightfall.

Even one missed night can result in disaster.

Remove attractants

Keeping the coop area clean helps reduce the risk of attracting rats, which in turn attract larger predators.

• Store feed in metal bins with tight-fitting lids.
• Clear up any spilled feed or scraps daily.
• Avoid leaving food out overnight.
• Keep grass short and remove clutter that could shelter rodents.

A tidy setup makes your site far less appealing to unwanted visitors.

Electric fencing for high-risk areas

For high-pressure areas, electric fencing can provide additional protection. When properly installed, it delivers a harmless but highly effective deterrent to foxes and badgers.

• Use poultry-specific fencing or multi-strand electric wire systems.
• Keep vegetation trimmed to avoid shorting.
• Check voltage regularly.
• Always follow manufacturer guidelines carefully.

In areas where fox activity is particularly heavy, I have seen electric fencing make a huge difference to long-term flock safety.

Inspect regularly

Predator proofing is not something you set up once and forget. Regular inspections are essential to maintain security.

• Check mesh fixings, latches and door mechanisms monthly.
• Look for signs of digging, gnawing or weather damage.
• Replace worn or damaged parts promptly.

Early repairs prevent small weaknesses becoming serious vulnerabilities.

A secure setup gives long-term peace of mind

Predator attacks are sadly common, but nearly always preventable with the right precautions. In my opinion, the best way to predator proof a chicken coop and run is to invest in a properly designed coop, reinforce your run, secure all weak points, and stay vigilant. This will give your chickens the safe, secure environment they need to thrive and help you sleep easier at night.
