Egg Farmers of Canada says there's been a big drop in the industry's impact on the environment.
A study done for EFC suggests the environmental footprint of the country's egg production supply chain dropped almost 50 per cent from 1962 to 2012.
That same study indicates farm gate impact for eggs produced in conventional housing systems dropped by a third over that 50 year period.
CEO Tim Lambert argues that while egg production increased by more than 50 per cent in that time, the sector's overall environmental impact dropped in all emissions and resource use domains.
The study suggests one of the reasons for that increased environmental sustainability is changes in the composition of the feed used for chickens.
Other factors include fertilizers, improved animal health and higher productivity in pullet and egg production.
