How chicken food changes egg nutrition
Effect of oil blends with near equal increases in 18 carbon n-3 and n-6 fatty acids on fatty acid profile of eggs

Chickens can't break down certain fats in their food, so those fats go straight into the eggs they lay. This study tested different healthy oils in chicken food to see which ones make eggs healthier.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Feeding hens a special fat called gamma-linolenic acid (GLA) boosts certain healthy fats in their eggs more than another fat called linoleic acid (LA), and it might skip a slow step in the process — meaning more of the good stuff ends up in the yolk.
Feeding hens a special fat called gamma-linolenic acid (GLA) helps their bodies make more healthy fats for the egg yolk—16.7% better than another fat called linoleic acid—because GLA skips a slow step in the process.
If you feed laying hens oil rich in a fat called SDA, their eggs end up with way more of the good omega-3 fats—like EPA, DPA, and DHA—compared to feeding them another plant-based omega-3 oil. This happens because SDA skips a slow step in the hen’s body that usually holds back omega-3 production.
Feeding hens a certain type of fat called stearidonic acid helps their bodies make more healthy omega-3s in egg yolks—43% better than another fat called ALA—because it’s easier for their bodies to process.
Feeding laying hens a type of fat called stearidonic acid boosts a specific liver enzyme that helps make longer fatty acids more than other fats do.
