Yolk color is determine by the feed. Free range chickens can have a wide range of color. A high corn diet or free range hens eating lots of green can produce yellow skin and very dark orange egg yolks. My hens yolks get orange in the fall when they eat large amounts of squash in the garden. Eggs produced on a commercial farm often add pigmenting carotenoids to the feed because consumers equate dark yellow yolks with quality eggs.
No Brighter color reflects only the nutrition of the hen. The richer the color of the yolk indicates the quality of the food the hen is eating. Most free range hens lay eggs with bright orange yolks.
Double yolks are not that rare. Double yolks are a result of two ovum being released to the hens oviduct at the same time.
Yes Cut small or shred,and they make good snacks for chickens. Feed them enough and you can change the color of their egg yolks. Beta Carotein makes egg yolks darker. Whole carrots are to hard and large for the hens to break off pieces and they give up trying to eat them.
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, etcAllow 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.
All eggs have yokes, this is the nucleus of the cell. However, hens lay eggs without fetuses inside when the eggs are not fertilized by a male rooster.
If you mean meat, then no.
some milk
Yes, it is recommended to feed hens laying food once they are old enough, even before they begin laying eggs. Laying feed is specially formulated to provide the necessary nutrients for egg production and can help support the health of the hens as they prepare for laying.
maybe i dont know
The same as other laying hens - layer feed, preferrably organic crumbles.
Our roosters eat the same feed as the hens. It is a basic ration for egg laying poultry purchased up at the tractor supply. They also get veggie and salad scraps from the kitchen. They don't mind getting into my garden and eating my greens and strawberries either.
