Bird Flu and the Backyard Poultry Keeper

I recall the morning of the 7th of December 2016 as being much like any other at that time of year. It was dark outdoors as I filled the kettle and switched on the radio. The weather had turned slightly mild and damp after a nice spell of icy cold weather. I remember thinking we could have done with another week of the cold weather just to ‘clean the ground’. The poultry really do seem to benefit from seasonal shifts like that as opposed to the mild merge of muddy autumn into murky winter. Aside from that, they always look resplendent free ranging on a frosty, bright day.

Routine had the radio playing the Today programme on Radio 4 and it’s not every day that poultry makes it on to the news. No surprise then that myai-symptoms ears instinctively pricked up as the Chief Vet came on air and informed the reporters that due to outbreaks of a highly pathogenic strain of avian influenza which is sweeping across Europe, DEFRA have invoked a precautionary “prevention zone”. This order required all poultry and captive birds to be kept indoors for 30 days in order to reduce the risk of possible infection occurring from domesticated birds coming into contact with infected migratory wild birds. Initially this only impacted England however within days Wales and Scotland quickly followed suit and the zone became UK wide.

ai-transferIt had been on the cards. I had been following the discussions taking place between the authorities and the industry during the autumn as I recall the spectre of the AI hovering over the country a decade ago. The impact that had still resonates, but for me it is not so much from an industry perspective, but from that of the backyarder and smallholder.

I haven’t done the maths but I suspect I wouldn’t be far wrong to say that 98% of the poultry in the UK is owned by 2% of the poultry keepers and as such a large element of the risk can be managed with a plan that works for a small minority of keepers. The reverse is, 98% of poultry keepers owning 2% of the poultry and these are dispersed and relatively unregulated and unmonitored.

ai-free-rangeWe are predominantly free rangers who view a chicken coop as a place where the birds roost and lay their eggs. as opposed to a building where the flock can be contained for 30 days, and there lies the crux. Precautionary prevention zones are sensible and far more desirable than an outbreak and the subsequent indiscriminate destruction of birds that fall within that biohazard zone, and I suspect that if the action is successful (measured on the basis of no infection occurring whilst the order is in place) then they will become a more frequent occurrence.

Commercial keepers of thousands of birds have the capacity to contain their flocks within the sheds has been analysed and generally agreed as a feasible approach but what of the small scale keeper?

DEFRA have state the “The Prevention Zones requires all poultry and captive birds, including backyard flocks and other captive birds, to be housed or, where it is not practicable to do so, requires steps to be taken to keep them separate from wild birds. If you keep your birds near your home, consider housing them in alternative accommodation, such as a garden building, a garage or redundant building that could be adapted to house your birds temporarily.”

This is sound advice for those who have such buildings and DEFRA went on to say “Remember to check for, and remove, hazardous and toxic substances such as rat bait, and make sure the birds have access to water and somewhere to perch. You must also practice good biosecurity – for example disinfecting footwear and equipment and washing clothing after contact with birds.”

Victoria Roberts, one of Britain’s leading poultry vets, and fellow magazine contributor, when asked what action smallholders and back garden poultry keepers should take said “In its most pragmatic terms, ‘indoors’ means protection from wild bird faeces, so a covered run is better welfare for chickens than being shut in a dark shed. Free range hens will need entertainment if suddenly confined, such as branches for extra perching, vegetables hung up etc. to avoid conflict.”

One twitter user asked me if wire mesh over the top of the run would be enough to keep her flock safe. I reminded her that bird faeces would still be able to drop through the mesh and that a tarpaulin cover would prevent this, but to ensure it had slight tilt on it so that rain (and snow) could run off safely and away from the flock underneath.

Victoria has also echoed this point adding “The birds need to be kept in the hen hut until the keeper can construct a makeshift run that is covered.”

It is ultimately a case of common sense as this disease is no different than many in that it is spread through:

  • movement of poultry, people, vehicles and equipment between and within locations;
  • the introduction of birds of poor or unknown health status;
  • contact with other flocks;
  • using shared equipment and vehicles, which have not been effectively cleansed and disinfected;
  • contact with vermin or wild birds;
  • birds drinking from contaminated water sources;
  • birds eating contaminated feed;
  • unsatisfactory cleansing and disinfection of vehicles, sheds, feeding troughs and other equipment.

The objective therefore is to remove, or at least dramatically reduce, the risk of your flock coming into contact with wild birds or their faeces. Here are some specific considerations for when a prevention zone is invoked.

 

Keep the flock indoors – if this is possible then it is the easiest option but observe the welfare needs of the birds closely by increasing your cleaning regime, providing additional items of interest for your flock, and observing a tight biosecurity plan to reduce the risk of infection being carried into the housing. It should go without saying but any proposed building must also take into account the importance of adequate ventilation.

Keep the flock runs covered – permanent indoor housing might not be possible it which case a cover over the run is needed. Small gauge mesh will only stop birds from entering the run and whilst better than nothing at all, a solid cover is far superior at reducing the risk. Consider erecting a solid lean-to on the side of existing houses, this could be a fence panelling for example, or adapting a fruit cage using tarpaulin. Creating temporary outdoor pens using straw bales and a tarpaulin roof with small gaps for light and ventilation is another option. Be aware though if bad weather is likely to be a problem, it may be necessary to erect a windbreak around your structure.

Keep moveable coops in the same place – if your birds are housed in moveable arks or tractor units then don’t be tempted to move the house to fresh ground. This will simply increase the possibility of your flock coming into contact with wild bird faeces.

Keep your access to the housing and run area to a minimum – by doing this you will reduce the risk of you contaminating the area with wild bird faeces you may have come into contact with elsewhere on your property

Keep your equipment clean – use disinfectant such as Virkon to keep equipment and footwear clean, and ensure the clothing you use when working with your poultry is washed after contact with birds.

Keep feed and water out of the reach of wild birds – make sure that drinkers are under cover and ideally put feeders in the coop. Avoid placing water in the house unless you are using nipple drinkers; regularly drinkers will get knocked over in any skirmishes in the coop.

Keep your birds contained – avoid unnecessary handling and movement of your birds on or off site, and where practical avoid visiting other poultry keeping establishments to reduce any possibility of cross contamination.

Keep a close eye on your poultry – if you have any signs of illness then seek advice from a qualified vet.

 

The 6th of Jan is when the restrictions are due to be lifted however time will tell if the pre-emptive action has paid dividends, but more over whether all 100% of the UKs poultry keepers have conformed and made their contribution to keeping the UK bird flu free.

  1. Great article. I had heard about the UK quarantine and wanted to read more about it. As a chicken keeper myself here in the US where the avian flu hasn’t yet been able to take hold, I’m obviously concerned and interested in keeping up with the latest. I will share with my Facebook followers this weekend, many of whom do live in the UK.
