Free run eggs are laid by hens housed in barns equipped with nests and perches. More space to scratch, peck and stretch their wings means less stress for the birds.

In the case of free range eggs, the hens can roam inside barns as well as outdoors, weather permitting. Outside, they can sunbathe, dust bathe, and eat bugs, worms and grass.

Are organic eggs the best eggs?

When a carton of eggs is labelled as “organic,” it means the hens’ feed is free of herbicides, pesticides, fungicides and preservatives. A study by researchers at Pennsylvania State University found that organic eggs tend to have more vitamin A, D and E. 

What’s more, many pro chefs claim they taste richer. Certified organic farms adhere to specific standards and are inspected regularly, making their products the surest choice.

What does it mean when eggs are Omega-3-enriched?

The label “Omega-3-enriched” indicates the hens laying the eggs were fed high levels of polyunsaturated omega-3 fatty acids – essential dietary nutrients for human growth, development and general health. 

In most cases, flaxseed or fish oil has been added to the feed, occasionally lending the eggs a mild fishy flavour and aroma.

The best eggs for baking

From peewee to jumbo, eggs are graded by weight. Unless otherwise specified, choose large eggs (approximately 60 grams) when following recipes – especially when baking, where precision matters.

Health matters

Pregnant women, young children, the elderly and people with compromised immune systems should stay away from raw or partially cooked eggs to avoid the risk, however slight, of salmonella poisoning.
