If you feed pasture-raised chickens extra grass-fed beef fat and liver, their egg yolks end up with five times more 'good fat' called CLA — about 0.05 grams in every 100 grams of yolk — compared to...

Feeding laying hens a diet with 6% of energy from alpha-linolenic acid changes the fatty acid composition of their eggs, lowering the omega-6 to omega-3 ratio from 7.17 to 1.29 and making the lipid profile more balanced.

Feeding laying hens linseed oil at 2.5% in their diet increases the omega-3 fatty acid content in their egg yolks by 13.6% and lowers the omega-6 to omega-3 ratio from 4.95 to 1.01, changing the fat composition of the eggs without affecting how many eggs are produced.

When laying hens are fed feed with less linoleic acid, their eggs contain more long-chain omega-3 fatty acids because the hens convert more of the alpha-linolenic acid in their diet into these fatty acids.

Laying hens fed a diet where 6% of the energy comes from alpha-linolenic acid produce eggs with nine times more omega-3 fatty acids and a much lower omega-6 to omega-3 ratio than hens fed a diet with 0.3% alpha-linolenic acid.

Eggs from chickens fed beef fat and liver have way more of certain healthy fats than regular cage-free eggs — up to 70 times more in some cases — because the fats from the beef end up directly in the eggs.
