What makes egg yolks darker?

Answer 1

For your hens to have a richer, more dark yolk, do these things -

• Feed your hens a much more varied diet. Layer food should be the staple, but supplement their diet!!! Feed them treats like cooked eggs (for protein, and to help discourage eating raw eggs in the laying boxes), oats, fruits (no citrus!), veggies, etc
• Allow them to free-range. This is a important factor.
• Make your hens as happy as possible. Most famers say that a happy hen will lay more often, and lay a better egg. It is well known knowledge that a hens laying cycle can be affected by stress - try to cut it down to a minimum.
