Do You Need a Chicken Run Cover? A Practical Guide for UK Keepers
A chicken run cover is not always essential, but for most UK keepers it is one of the most practical additions you can make to your setup. If you keep chickens through a British winter, the question is less "do I need one?" and more "why haven't I fitted one already?". There are also circumstances, when DEFRA issues an Avian Influenza housing order, when a covered run stops being optional altogether.
What Does a Chicken Run Cover Actually Do?
A run cover does four distinct things, and it is worth understanding all of them before deciding whether one suits your setup.
Keeps the run floor dry
This is the reason most UK keepers end up buying one. In a wet UK winter, a bare soil run without cover can become unusable within a few weeks. We have spoken to keepers who effectively lost their run to mud from October through to April because they had not covered it. The hens stop ranging willingly, the ground becomes difficult to walk on, and managing the run becomes a lot more unpleasant than it needs to be.
A cover fitted over the run stops most of the rain reaching the ground directly. Combined with a suitable ground cover material (bark chip, horticultural sand or Aubiose hemp bedding) a covered run stays in usable condition through even a difficult winter.
Provides shade in summer
This one surprises some keepers. Hens do not tolerate heat as well as many keepers expect. A covered run with shade netting can make a real difference on a hot UK summer day, giving your flock somewhere cooler to rest without having to bring them inside. It also protects hens from direct UV exposure for extended periods, which matters more on south-facing runs.
Reduces the risk from wild birds
Wild birds landing in or near a run bring droppings with them, and with those droppings comes potential disease risk. A solid or close-mesh cover acts as a physical barrier between your flock and passing birds. This is relevant during periods of heightened biosecurity concern. Our Biosecurity Measures guide covers this in more detail if you want to understand the broader picture.
Satisfies DEFRA housing requirements during Avian Influenza risk periods
When DEFRA issues a housing order during an Avian Influenza (HPAI) risk period, all poultry must be kept under cover. A run with a solid or close-mesh roof fitted, and with the sides enclosed, can satisfy this requirement without having to keep your hens locked inside the coop itself. This is a significant welfare advantage if housing orders last for weeks rather than days.
When Does a Run Cover Become Compulsory?
DEFRA and the Animal and Plant Health Agency (APHA) issue housing orders when Avian Influenza risk is elevated. In recent years, these orders have been declared most commonly in autumn and early winter, coinciding with the arrival of migratory wild birds that can carry the virus. During a housing order, all poultry must be housed. Free-ranging is not permitted.
A fully enclosed run with a solid or close-mesh roof fitted counts as housing for the purposes of a DEFRA order, provided the sides are also properly enclosed and there is no meaningful wild bird access. Keepers who had a covered run already in place when the last housing orders came in were significantly better placed than those who had to improvise suddenly. Fixing a cover quickly, under pressure, with the order already active, is a different experience from having one fitted calmly in September before the risk period begins.
If you are unsure whether your covered run would meet the standard, the key test is whether wild birds could realistically access it from above or the sides. If they cannot, it should satisfy the requirement. If in doubt, contact APHA directly.
The DEFRA housing order situation changes from year to year and sometimes from month to month. Check the APHA website for the current status and guidance on what qualifies as adequate housing. Our Biosecurity Measures article also covers flock registration and notification requirements that go alongside housing orders.
Does a Chicken Run Cover Prevent Mud?
For most keepers who are not in the middle of an AI housing order, the day-to-day reason to buy a run cover is mud. The UK climate is not kind to unprotected runs. A grassy run can be reduced to bare soil within a few weeks of a new flock arriving. Once the grass is gone and rain arrives in earnest, the soil becomes mud, and mud becomes a genuine welfare concern.
Hens standing in wet mud are more susceptible to foot problems including scaly leg and bumblefoot. They are also less likely to range willingly, which defeats part of the purpose of having a run. And from the keeper's perspective, managing a muddy run is significantly more work: harder to clean, unpleasant underfoot, and difficult to rake or turn over.
A cover that keeps most of the rain off changes this substantially. It will not keep the run completely dry in heavy, driving rain, but it reduces the water load on the ground enough to make a real difference. Working alongside a good ground cover material, a covered run can stay in excellent condition through a British winter rather than needing to be abandoned until spring.
The combination that works best is a waterproof run cover fitted over a metal chicken run with good drainage, topped with 5–8cm of bark chip or Aubiose hemp. Metal runs with welded or bolt-together frames are well suited to run covers because they have consistent fixing points along the top rail and across the structure.
Waterproof Covers vs Shade Netting: Which Do You Need?
These are two different products that solve different problems, and some keepers use both at different times of year.
Waterproof and polycarbonate-style covers
Heavy-duty tarpaulin covers and polycarbonate panels both block rainfall and provide a dry area beneath them. They are the right choice if your main concern is mud, winter weather or satisfying a DEFRA housing order. The trade-off is airflow: if you cover the entire run roof with a solid or near-solid waterproof material, ventilation can be reduced. The practical fix is to leave a gap at one or both ends rather than covering the full length, which maintains airflow without losing most of the weather protection.
Polycarbonate panels transmit light while blocking rain, which means the run stays brighter than it would under a solid cover. They are also more durable than tarpaulin-style covers over time, though more involved to fit to an existing run frame.
Shade netting
Shade netting is a breathable, open-weave material that reduces UV light and air temperature without blocking rain. It is the right choice if your main concern is summer heat. It allows airflow freely, which helps on hot days and avoids creating a trapped, humid environment in a run that is already enclosed on three or four sides.
Shade netting alone does not satisfy a DEFRA housing order requirement. The mesh is too open to prevent wild bird access, and it does not keep rain off the ground. If you use shade netting for summer and want to be ready for housing orders in autumn and winter, you need a second cover available that can be fitted when required.
Some keepers keep both on hand and swap depending on the season. This is a practical approach, and for larger runs where it is not difficult to fit and remove covers when needed, it works well.
How to Measure Your Run for a Cover
Getting the measurement right before you order means the cover fits properly and stays in place.
Measure the full length of the run from end to end at the top rail. Then measure the full width from side to side at the widest point, also at the top. These are your two dimensions.
Add 10–15% to each measurement to allow for overlap at the edges and enough material to secure the cover to the frame. A cover that reaches exactly to the edge of the run will move in wind and let rain in at the sides. You want material that folds down and can be fixed or weighted along the frame.
Consider the pitch of the cover. A completely flat cover will pool water in the centre under sustained rain, which adds weight and can stress a lighter run frame over time. Fitting the cover with a slight angle, even just a few centimetres of drop from one side to the other, allows water to run off rather than accumulate. On a standard rectangular run, this usually means fixing one long edge slightly higher than the other.
Finally, check the fixing points on your run frame before ordering. Most metal runs have fixing points or rails along the top that a cover can be tied, clipped or tensioned onto. Make a note of the spacing and the type of attachment point so you know what you are working with when the cover arrives.
Year-Round vs Seasonal Use: Which Approach Works Better?
Both approaches work. The right one depends on your setup and how much work you want to do fitting and removing the cover each year.
Some keepers fit a permanent cover and leave it in place. This works well on a metal run with a well-fitted cover designed to stay outside in all weathers. A permanent cover means you are ready for housing orders without any preparation and your run floor stays in consistent condition year-round. The main consideration is ventilation in summer. A run that is permanently covered needs good airflow from the sides to avoid becoming warm and humid in July and August.
Other keepers put a cover up for autumn and winter and remove it in spring. This gives more airflow in summer and avoids UV degradation of the cover material during the brightest months. UV degradation is the most common failure point for polycarbonate panels and tarpaulin-style covers over time. A cover that spends six months in storage rather than twelve months exposed to the elements will last longer.
Whichever approach you take, check the cover and its fixings at least once a year. Look for wear at the attachment points, any pooling or sagging in the middle, and any thinning or brittleness in the material. Catching a small repair early is easier than dealing with a cover that fails during a housing order or a wet week in November.
Frequently Asked Questions
Does a chicken run cover help with mud?
Yes, and for most UK keepers this is the single most practical reason to fit one. A waterproof cover stops most rainfall reaching the run floor directly, which keeps the ground significantly drier. It works best when combined with a ground cover material such as bark chip, sand or Aubiose hemp bedding. A covered run over good-draining ground can stay in usable condition through a UK winter rather than becoming muddy and unmanageable.
Do I need a run cover for the bird flu housing order?
When DEFRA issues an Avian Influenza housing order, all poultry must be kept under cover. A fully enclosed run with a solid or close-mesh roof fitted can satisfy this requirement, provided wild birds cannot access it from above or the sides. A shade net alone does not satisfy the order. It is too open. If housing orders are a realistic concern, a waterproof or solid-mesh cover is worth having fitted and ready before autumn.
What is the best type of chicken run cover for UK weather?
For the UK climate, a heavy-duty waterproof cover or polycarbonate panels are the most practical choice for most of the year. Polycarbonate panels transmit light and are durable long-term. Tarpaulin-style covers are easier to fit and remove and work well for seasonal use. If summer heat is also a concern, shade netting is worth having as well. Some keepers use waterproof covers in autumn and winter and switch to shade netting for the warmer months.
How do I fix a cover to a metal chicken run?
Most metal chicken runs have a top rail or fixing points along the frame that a cover can be attached to. Common methods include bungee clips or cable ties through grommets in the cover edge, tension straps run under the frame, or purpose-made cover clips if the manufacturer supplies them. Fix the cover at regular intervals along all four sides so it does not lift or shift in wind. Leave a gap at one or both ends if the run is fully enclosed to maintain ventilation.
