If you asked most people what color egg yolk are , they would likely answer chickenhearted .
Yolks have always been associate with the colour yellow , which is unfortunate because backyard chicken keeper know better .
Backyard chicken keeper get it on that yolks can — and should — be a bright , sheer orangeness , and those shining , bluff orangish yolks are a sign of happy , healthy hens .
In an unscientific home experimentation , I compare my grazing land - forage , insect - pecking , soil - scratching , whole texture - feedingchickens ’ yolks to the yolks of both their “ barren - stray ” and factory - farmed counterparts .
The event were clearly visible : Yolks from my homegrown egg were not only darker , but also fuller and thicker . Even the eggshells were denser and harder to crack .
But what ’s the big passel about orange tree yolks ?
deform out that besides being a coveted color , orangish egg yolk can be an indication of a well balanced and extremely nutritious dieting .
What makes egg yolks orange?
A few thing broker into the fashioning of an orange yolk : xanthophylls , omega-3 fatty acids , and meats .
Xanthophylls
The chemical substance responsible for egg yolk coloring were firstdocumented in 1915 in the Journal of Biological Chemistry .
Dr. Leroy Palmer wrote that “ The consumer demands highly colored yolks in ‘ fancy ’ testis throughout the year , and the eggs with pale color in egg yolk , so frequently found on the market place during the winter month , are the object of much complaint , particularly in cities . ”
He regulate that orange yolks were produced by a class of carotenoids called xanthophylls , and over 100 age by and by , this conclusion is still widely take over .
Carotenoids are raw plant paint found in many fruits and vegetables . It ’s often thought that beta - provitamin A , one of the more well - know carotenoid , is responsible for giving yolks the orange pigment that mass associate with carrots .
But in actuality , beta - carotin benefit yolk nutritionally , rather than paint - wise .

Thecarotenoids that cause deeper yolk coloringare xanthophylls , which are more readily absorbed in the yolks . ( Lutein is one such xanthophyll , and a lot of lutein mean a lot more orange . )
Xanthophylls are ascertain in dark leafy green like spinach , wampum , and collards , as well as in zucchini , broccoli , and brussels sprout .
( I know it seems unearthly that a carotenoid that turns ball yolks Orange River is found ingreenvegetables , but stay with me here . )

Omega-3 fatty acids
Omega-3 fatty acids are highly hard in oily Pisces ( specially cold - water Pisces like salmon , tuna , and mackerel ) , mollusk , algae , tofu , and high - fatty tissue industrial plant foods ( like brusssels sprout , navy bean , and Persea Americana ) .
They ’re also regain in flax seeds and ocean kelp , which are both significant components of myhomemade whole - caryopsis crybaby provender .
Meat
Did you bang that chickens are not meant to be vegetarian , no matter what your premium carton of organic / grain - fed / cage - free nut severalise you ?
Chickens are omnivores by nature and their healthiest diets include meats , such as mealworms , beetles , grasshopper , grubs , and whatever creepy - crawly they can pull out of the ground . I ’ve even heard of chicken attacking and feeding on small rodents and snake !
And yes , you’re able to even feed your chickens the remnant falsify chicken from last night ’s dinner ( no matter how wrong that may fathom ) . It ’s undecomposed for them , and wo n’t plough them cannibalistic .
Are dark orange yolks healthier for you?
Yes and no .
You see , coloralonehas very small to do with the nutritional substance of an ball vitellus . Yolk color depends almost entirely on the pigments found in the solid food that chickens eat .
When hens exhaust a diet that ’s heavy in white-livered corn , they lay eggs with medium - yellow yolks . A dieting of wheat or barleycorn results in eggs with lighter - colored vitellus , and a colorless diet ( such as bloodless corn ) produces nearly white yolks .
In fact , it ’s so gentle to “ dye ” the colour of a yolk that a Santa Fe , New Mexico husbandman , Matt Romero , is experience for his legendaryflame - colored egg yolk , which he gets simply by feeding his hen the leftover red chile peppers from his farm .
Other farmers “ hack ” their room to darker yolks by fertilise their plenty marigold petals ( which produce deep icteric yolks ) or evenusing synthetic chemicalslike Rovimix Carophyll Yellow , Canthaxanthin , Xanthophyll B , and Lucantin Red to achieve the dark yolks they retrieve their consumers prefer .
This is why you should be mistrustful of cheap egg from the supermarket whose egg yolk amount out orangish .
On the flip side , there ’s cause for concern if store - corrupt “ free range of a function ” or “ pastured ” eggs have very pale yolks . It could intend the egg producer is only giving the hen minimum accession to the open , like a single door out to a plot of ground of sens .
Foods That Naturally Impact Egg Yolk Color
But , there ’s a bigbutto all this …
Chickens whose diets are rich in leafy greens , flowers , seeds , weeds , and center lay eggs with naturally dark yolks . The xanthophylls , omega-3 fatso acids , vitamin , and mineral in these food source are then decease on to their eggs and concentrated in their egg yolk .
Research has shown that of all the nutrition found in eggs , most of it is found in egg vitellus , include fat - soluble vitamin like D , E , K , and A ( none of which you get from testicle whites ) , essential fatty battery-acid like DHA and ALA , and other nutrients like calcium , smoothing iron , Mg , zinc , choline , and B vitamin .
According toMother Earth News , which conducted its own egg analysis , and a more recentPennsylvania State University cogitation , pastured bollock ( where hen are grant free range with sizeable access to green and glitch ) contain higher levels of vitamin A , D , and E , more beta - carotene , and more omega-3s than ballock from caged chickens fed in the main cereal .
All this means is that a crop ball ( ideally from your own yard)ishealthier for you . And that ’s one of the reason we fire chicken , right ?
How to get dark orange yolks from your chickens
1. Let your chickens free-range.
Let your ladies swan a eatage ( or a garden — specially if you ’re dig over soil — or even just a young patch of dirt in their chicken tractor ) for an orange - boosting hemipteron buffet . They care to itch through leaf deal andlayers of mulchwhere protein - rich grub and tastyearwigs often blot out .
If it ’s recently rained , rent your chickens out so they can hunt for worms , sowbugs , slugs , centipede , and other bug that issue when things get more damp .
Pastures ( or backyard ) full of rich pasture , ground covers , andcover cropsare a wonderland for your sight , giving them mickle of chance for forage and physical exercise .
2. Feed your chickens lots of leafy greens.
Give your chickens plenty of fresh green to increase the lutein in their yolks .
The darker the green the serious , so I often pay back them a feast of comestible amaranth ( one of my favoritesummer super C ) , kale , mustard leafy vegetable , Brassica oleracea italica leaves , or whatever I befall to have turn in my garden .
If it ’s the heart of wintertime and your garden greens are lacking , you could give them alfalfa for a nutritional boost .
3. Let the chickens weed the garden for you.
Rather than displume all those ( vitamin rich!)weedsout of your garden , countenance your chickens do the lousy workplace ! They bed to forage fordandelions , mallow , trefoil , oxalis , chickweed , purslane , and other plants that sometimes grow where they should n’t .
In fact , these character of weeds can be cultivated in a landscape specially for your quite a little , as they ’re gloomy - maintenance and make a lovely , natural , and “ wild ” lawn that benefits other wildlife as well .

4. Enlist your chickens in yard clean-up.
Chickens are very ready to hand helpers at the end of the time of year when most of yourplants have boltedand becomeaphid - ridden .
Let the chickens clean up those industrial plant before you convulse them into the compost . It ’s a winnings for everybody ! ( Except the bug , that is … )
Not only will they take care of the pests on your spent plants , they ’ll eat whatever ’s go out on the stems , including flowers and seeds .
5. Let your chickens turn the compost pile.
If you have an undefended compost pile , Gallus gallus do good work of turning over yard debris and kitchen scraps as they scratch and pick up for eats and worms . ( bleak soldier fly larvae , which are commonly found in decaying organic matter , have even more protein than mealworm and are naturally mellow in calcium . )
you’re able to start a compost pile in a corner of the chicken run , or build up a compost bank identification number inside the run that ’s undetermined on one side ( and can be covered as needed ) .
The Gallus gallus will feed what they want , shred up your scraps for quicker composting , and keep themselves busy and entertained on days they ca n’t free - orbit ( which intend less hen pecking among the flock ) .
After a few calendar week , you ’ll be so used to seeing orange yolks ( the mode most of us have been conditioned to see yellow yolks ) that you might even think they have n’t changed in color .
Buy some nut from the shop and crack up them into a bowlful with your homegrown eggs — you’ll be stun at the difference !
