Managing a change to white, absolutely beaked birds requires shut consideration to element however can enhance manufacturing and welfare, based on Powys-based farmer Phil Davies.
Mr Davies and spouse Helen started free-range egg manufacturing in 2018 utilizing brown birds.
However the couple determined to maneuver to completely beaked white, Dekalb birds from their second flock after discussions with their egg packer, Stonegate.

With many retailers eyeing a transfer to completely beaked programs and the promise of a hardier fowl with larger longevity, the thought made sense.
Initially, Mr Davies mentioned he was involved in regards to the potential for elevated harm to the birds and what the impression can be on the day-to-day working of the flock.
However utilizing recommendation from suppliers and making minor changes to the administration has helped the Davies obtain a seamless transition.
That course of started by making certain the set-up of the rearing shed matched the laying shed to assist the pullets settle shortly on arrival.
The farm’s rearer makes use of a multi-tier association, which matches the system within the Davies’ 16,000-bird laying shed precisely.
“We’ve discovered that once they arrive, the pullets transfer up onto the tiers right away,” says Mr Davies.
This reduces the period of time spent dealing with birds to get them to make use of the system within the first few nights within the laying shed.
Within the present flock, simply 10 birds are dealt with every evening within the first few days, maintaining stress and flock disruption to a minimal.
In addition to matching shed structure to what the pullets skilled throughout rear, making certain the routine remained the identical helped the flock to settle shortly and begin gaining weight.
Initially, feeding instances and light-weight ranges match these from the rearing shed, however might be adjusted because the flock progresses.
For instance, lighting begins at 50% and is steadily decreased by small increments, bringing it right down to 30% by the point birds come into lay. This helps to take care of calm behaviour patterns among the many birds.
Transitioning to a farm with year-round earnings
Free-range egg manufacturing is just one a part of the Davies’ technique to earn a month-to-month earnings from their 121ha farm, close to Welshpool.
“We initially farmed sheep and beef, however we needed to maneuver away from solely having monetary earnings at two factors within the 12 months,” says Phil Davies.
In 2015, they launched a New Zealand-style dairy system, and now have a 200-cow Jersey-cross spring-calving herd.
The transfer into poultry got here three years later, when the primary flock of brown birds arrived.
“The change to white birds for the second flock decreased the administration necessities from the egg manufacturing facet of the enterprise, as we will maintain the flocks going for longer between turnovers,” Mr Davies says.
“Though I used to be initially apprehensive about maintaining absolutely beaked birds, with enrichment, constant routines and a focus to element within the lighting within the shed, we have now discovered them to be constantly calm and straightforward to handle.”
Provision of enrichment
Enrichment is necessary in absolutely beaked setups as a result of it permits birds to specific pure behaviour traits. Offering this outlet for exercise reduces the probability of feather pecking.
The Davies present a mixture of plastic bottles, containers and lucerne bales inside the shed.
These objects are closely used on arrival however because the flocks settle in, the birds’ curiosity wanes and they’re used much less, Mr Davies mentioned.
Nevertheless, with the avian flu housing order in place since November final 12 months, the farm has elevated the quantity of litter accessible to the birds to peck.
This has once more helped birds to specific pure behaviour and stored them calm even in the course of the lengthy winter months inside.
Monitoring and feeding
Within the 4 years since taking on poultry manufacturing, the Davies have labored carefully with Wynnstay guide Jim Turner.
He explains that Mr Turner and his crew supported the farm by monitoring the flock within the first few weeks. Chook weight achieve and general situation have been tracked and feed schedules have been adjusted accordingly.
Monitoring, together with the ensuing tweaks to the ration, have helped to optimise weight achieve and egg dimension all through a far longer lay than was seen with brown birds.
“Our present flock are attaining 89% egg manufacturing at 81 weeks,” says Mr Davies.
This efficiency far exceeds the common for the breed of 83.8%.
Flock turnover advantages
A part of the plan to change to white birds was analysis exhibiting that white birds have been usually hardier and simpler to take care of than brown hens.
That additional hardiness has contributed to the sustained stage of egg manufacturing and larger longevity.
The Davies plan to maintain the present flock to 93 weeks, which compares properly with the trade normal for brown birds of a 76-week cycle.
The additional 17 weeks of manufacturing at viable egg manufacturing ranges signifies that turnover price financial savings are equal to a complete new flock after three cycles.
Three consecutive flocks signifies that there was about 51 additional weeks of manufacturing, Mr Davies explains.
Reaching an extra flock will end in manufacturing financial savings – at £4.95 a fowl multiplied by a 16,000-bird flock, this equates to £79,200.
Wash-down and turnaround prices can be one other £4,800, which all provides as much as the price of a complete flock, he reckons.
Why atmosphere optimisation is important in absolutely beaked birds
Wynnstay poultry supervisor Jim Turner explains that profitable administration of absolutely beaked flocks centres on sustaining calm behaviour.
This prevents issues from arising, equivalent to feather pecking.
In lots of flocks, the inquisitive nature of hens leads to feather pecking.
Beak-trimming was launched to cut back the impact on the sufferer fowl. However a transfer again to completely beaked flocks carries an elevated threat of the difficulty growing into injurious pecking.
“Stress might be an influencing set off for the behaviour, so methods to minimise stress within the atmosphere are a should,” Mr Turner says.
He advises flock-keepers to start introducing processes that may restrict stress earlier than pullets even arrive on-farm.
Mr Turner recommends testing all tools – equivalent to followers, lights and pc programs – forward of the birds’ arrival, to keep away from any disturbance on account of tools issues within the first few days.
As soon as the pullets are settled, managers can steadily begin to acclimatise birds to the equipment noises and actions contained in the shed.
It will assist keep away from any stress triggers on the essential time once they begin laying.
Mr Turner additionally advises tailoring vitamin must the necessities of absolutely beaked birds, in addition to feeding instances.
With full beaks, birds are extra geared up to flick feed round, deciding on the morsels they need.
“This will drive up feed consumption figures, on account of elevated waste as feed finally ends up beneath the tracks.
“Getting a superb consistency of mash to cut back the sorting behaviour can, due to this fact, management feed prices.”
One other technique to chop waste is to feed little and sometimes, as this reduces the quantity of feed current.
In some circumstances, analysis has proven that feather pecking might be triggered by a scarcity of fibre within the food regimen, slightly than a stress response. Birds choose on the feathers to interchange the shortage of fibre.
An excellent indicator of that is the sudden absence of unfastened feathers within the corners of the shed.
“If that is so, fibre components might be launched to cut back the behaviour,” Mr Turner concludes.
