As British Summer Time ends on 28
October, science is helping farmers who supply
Waitrose with free range eggs to cope with the long nights in a sustainable way
Most of us know that chickens are seasonal layers and will naturally produce fewer
eggs as temperatures and daylight hours drop. Whilst electric lighting and heating
have long been used to maintain egg production levels, Waitrose has developed
sustainable methods to keep its Colombian Blacktail hens happy to lay.
Small mobile hen houses are fitted with low wind-speed turbines and photovoltaic
solar panels which generate up to 85% of the energy needed to power the units.
LED lighting has replaced the less efficient fluorescent lamps to mimick natural
sunrise and sunset, cutting power consumption by a third.
