Why are chickens yellow?

Answer 1

There are a few reasons this can happen.
As a hen ages out, and gets older she can stop producing good shell quality and cannot utilize the calcium she eats. She will still produce eggs but the shells can be soft and rubbery.
Poor nutrition is another reason hens will produce rubbery egg shells. This is easily remedied by the addition of high calcium foods and ground bone/oyster meal into their diet.

Answer 2

When our chickens were first laying eggs, their eggs had pale yolks. As they got older and we fed them grass cuttings or just pulled fresh grass and gave it to them to eat, their yolks seemed to get much brighter. Check with your local feed store or vet to see what you can add to the chickens diet. I prefer the organic method. I feed them chick=grow for the first year. Then I switch to laying pellets. I also give them crushed oyster shell. They love it and it makes their egg shells stronger. I grow grass especially for the chickens. I pull it each day and give them a bit. They peck the heck out of it and it's supposed to make the yolks richer. Check with your vet or local feed store.

Answer 3

Most chickens are not yellow. A lot of chickens come in other colour varieties except yellow: black, white, brown, or a mix of all three. Chicks, the offspring of chickens, are primarily yellow, but they lose their baby downy feathers and are replaced with different coloured adult feathers when they reach a few weeks of age.
