Cage-free farming is better for hens.
- On caged farms, each hen is forced to live her life in a space smaller than a standard sheet of notebook paper. She has little room to stretch her wings or turn around.
- Hens kept in such cages often suffer from feather loss, bruises and abrasions due to constant rubbing against the wire bars of the cage and other hens.
- The lack of exercise can make a hen’s bones brittle and leave her more vulnerable to injury and disease. Some hens are too unhealthy to even stand up.
- The small, barren cage restricts most of the hen’s natural behaviors. She cannot lay her eggs in a nest, perch, forage or dust bathe. Nesting is particularly important to hens and they experience extreme stress when they cannot lay their eggs in a nest.
Cage-free farming is safer.
There is overwhelming scientific evidence to demonstrate that caged hens have a greater chance of being infected by Salmonella; which is among the most common causes of food-related hospitalization and deaths in the US and Canada.ii,iii,iv
- A study by the European Food Safety Authority, which analyzed data from 5,000 egg farms in more than 20 countries, found up to 25-times greater odds of Salmonella infection in farms where hens were kept in battery cages than in farms using any non-cage system. i, ii, iii, iv, v, vi
- Keeping hens in small, barren, crowded cages causes them considerable stress, which can make the hens more susceptible to diseases and more infectious.
- Diseases can spread more rapidly in larger, denser flocks. The average size of a caged flock in the U.S. is 75,000 to 100,000 hens while the average size of a cage-free flock is 25,000 hens. A USDA study found that farms with more than 100,000 birds were four times more likely to have birds test positive for Salmonella than those with fewer than 100,000 birds.
Cage-free farming is better for everyone.
Whenever we buy eggs – or any product made with eggs – we’re making a choice about the kind of food we want to serve at our table, as well as the kind of world we want to live in. We have a responsibility to treat the animals that produce our food in a humane and decent way.
Change is possible! It begins with a simple choice. Buy cage-free eggs, every time – and encourage others to do so. A few extra dollars can help end the vast suffering of millions of hens– while providing a safer and more wholesome product for you. Join the flock — choose cage-free.
