When it comes to chicken, it's not uncommon to come across different colors of meat, ranging from bluish-white to yellow. The variation in color is primarily due to the chicken's diet, breed, genetics, and age. Specifically, the yellow hue in chicken meat is caused by the presence of carotenoids in their feed, such as corn, grass, or marigold flowers. Marigolds, in particular, have been added to chicken feed to enhance the color and improve meat quality. While the color of chicken meat may vary, it does not necessarily indicate a difference in quality or flavor.

What You'll Learn
Chicken colour is influenced by diet, species, exercise, age and genetics
Chicken colour is influenced by a multitude of factors, including diet, species, exercise, age and genetics.
Firstly, the colour of chicken meat can vary from bluish-white to yellow, and this is considered normal. The specific colour of the meat is influenced by the bird's diet, with corn-fed chickens tending to have yellower breasts. Marigolds, which are sometimes added to chicken feed, can also impart a yellow tint to the skin, flesh and egg yolks. This was famously used by Frank Perdue in the 1940s as a marketing tactic, where the golden colour became associated with health and premium quality.
The species and genetics of the chicken also play a role in the colour of the meat. Different breeds of chickens will have varying natural colours, and genetics can further influence this through specific genes and alleles. For example, the E-locus alleles influence plumage colour and can also affect skin colour. The sex of the chicken also influences colour, with males and females exhibiting different patterns and colour distributions.
Exercise and age are additional factors that can affect chicken colour. Free-range chickens that are active and spend their days searching for food tend to have firmer meat. Younger poultry has less fat under the skin, which can result in a bluish cast, whereas older chickens may develop rusty or brownish tints.
In summary, the colour of chicken meat is influenced by a complex interplay of factors, including diet, species, genetics, exercise and age, each contributing in unique ways to the final colour of the meat.

Marigolds in chicken feed can cause yellow pigmentation
The colour of chicken meat is influenced by a variety of factors, including breed, genetics, exercise, age, and nutrition. While corn in a chicken's diet can lead to a yellowish hue, it is not the primary cause of the deep yellow pigmentation that consumers often associate with high-quality, free-range chicken.
Marigolds, or more specifically, marigold extract, are added to chicken feed to enhance the yellow pigmentation of chicken meat and egg yolks. This practice dates back to the 1940s when Frank Perdue, who took over his father's farm, marketed chicken with golden-coloured flesh as a premium product. Marigolds are rich in lutein, a type of xanthophyll carotenoid pigment, which is absorbed into the chicken's body and deposited in its fat, skin, and egg yolks. The intensity of the yellow colour is directly related to the amount of marigold or lutein in the chicken's diet.
Adding marigolds to chicken feed has additional benefits beyond pigmentation. Marigolds are a natural source of antioxidants, which can improve the overall meat quality and act as a preservative. They also have insect-repellent properties, reducing the need for antibiotics in poultry farming.
It is important to note that not all yellow chicken is naturally yellow. Some producers add synthetic or natural xanthophylls to chicken feed to enhance colour and appeal to consumer preferences. While this practice is generally considered safe and regulated, consumers should be aware of the potential for unnatural pigmentation in their food choices.
In summary, marigolds in chicken feed can indeed cause yellow pigmentation in chicken meat and egg yolks. This practice has been used to indicate higher-quality, free-range chicken and has additional benefits for meat quality and preservation. However, consumers should be discerning and consider factors beyond colour when making food choices.

Corn in chicken feed can cause yellow pigmentation
The colour of chicken meat is influenced by several factors, including the chicken's diet, breed, genetics, exercise levels, and age. While it is common for raw chicken to range in colour from bluish-white to yellow, the yellow pigmentation is often more noticeable in cooked chicken.
Corn in chicken feed can indeed cause yellow pigmentation in chicken meat. Chickens that are fed a diet rich in carotenoids, including corn, will exhibit more yellow skin and fat. This is because carotenoids are yellow-orange pigments found in certain vegetables and grains, such as corn. However, it is important to note that simply feeding a chicken corn will not result in yellow flesh. The chicken's diet must be exclusively or primarily corn-based to achieve this effect. In addition, the chicken's breed and genetics also play a role in the intensity of the yellow pigmentation. For example, broilers, which are commonly raised for meat, often show more yellow colouring due to their genetic traits.
While corn can contribute to the yellow pigmentation in chicken meat, other factors, such as marigold petals in the feed, can also enhance this colour. Marigolds have been used by farmers for their nutritional benefits and insect-repelling properties. Additionally, they impart a deep yellow-orange tint to the chicken's skin, flesh, and egg yolks. This practice was popularised by Frank Perdue in the 1940s, who marketed the golden colour of chicken meat as an indicator of premium quality and health.
It is worth noting that the yellow pigmentation in chicken meat due to corn or marigold feed is generally safe for consumption and does not affect the flavour or nutritional value. However, some consumers may find the yellow colour visually unappealing. Nevertheless, it is important to be aware of other indicators of spoilage in chicken meat, such as grey or green flesh, yellow fat, or the presence of an unusual smell or slimy texture, which may suggest bacterial growth.
In summary, corn in chicken feed can be a contributing factor to the yellow pigmentation in chicken meat, along with other factors such as breed, genetics, and the presence of marigold petals in the feed. While this discoloration may be off-putting to some consumers, it is generally safe to consume and does not impact the nutritional value or flavour of the meat.

Yellow chicken meat is not fattier than white chicken meat
The colour of chicken meat varies from bluish-white to yellow, and this difference in pigmentation is often mistakenly associated with meat quality. However, yellow chicken meat is not fattier than white chicken meat. The colour of chicken meat is influenced by various factors, including breed, genetics, nutrition, and age.
Nutrition is a significant factor contributing to the colour variation in chicken meat. Chickens fed with corn, fresh grass, or marigold flowers, which contain carotenoids, exhibit a yellowish tint in their skin and flesh due to the accumulation of pigments in their lipid tissues. On the other hand, chickens fed with wheat, soy, or sorghum tend to have whiter and pinker meat. While marigolds are added to poultry feed as a nutritional supplement and to enhance colour, they do not indicate higher fat content in the meat.
The perception of yellow chicken meat being of higher quality may stem from marketing strategies, such as Frank Perdue's association of golden-coloured meat with premium quality. Additionally, in some countries like Mexico, yellow chicken meat is perceived as an indication of free-range chickens with better living conditions and welfare standards. However, this perception does not correlate with higher fat content in the meat.
The colour of chicken fat can vary between yellow and white, depending on factors such as diet, age, and breed. For instance, grass-fed cattle tend to have yellower fat due to higher levels of beta carotene in their diets. However, this variation in fat colour does not indicate higher fat content in yellow chicken meat compared to white chicken meat.
In summary, while yellow chicken meat may be perceived as higher quality due to its colour, it is not fattier than white chicken meat. The colour variation in chicken meat and fat is primarily due to dietary factors and other breed-related characteristics, which do not directly influence the fat content.

Yellow chicks are stained by the yolk
The colour of a chicken is influenced by several factors, including breed, genetics, exercise, age, and nutrition. While the yolk does not directly stain the chick, the colour of the chick is influenced by the same pigment that colours the yolk.
Chicks that will be white as adults are born with white down feathers that are light enough to be stained by the pigment in the yolk. This is why some chicks are yellow, while others are not. The yolk pigment stains the down feathers of the chick, but these feathers are eventually replaced by juvenile and adult feathers, which are not stained.
Genetics plays a significant role in the colouring of newly hatched chicks. Domesticated chickens with yellow skin possess a recessive allele, while white-skinned chickens carry the dominant allele. The yellow skin allele is influenced by the presence of carotenoids, primarily xanthophylls, in the feed. Carotenoids are pigments found in corn, fresh grass, and marigold flowers. When chickens consume these carotenoid-rich foods, the pigments accumulate in their lipid tissues and skin, resulting in a yellowish hue.
In addition to carotenoid-rich feed, marigold flowers are sometimes added to poultry diets. Marigolds provide nutritional benefits, ward off insects, and impart a yellow colour to the skin, flesh, and egg yolks. This practice became popular in the 1940s when Frank Perdue, a large-scale chicken wholesaler, marketed golden-coloured chicken flesh as a sign of premium quality.
It is important to note that the colour of chicken meat can vary from bluish-white to yellow, and all these colours are considered normal. The shade of the meat is not an indicator of quality, and consumers should refer to labels to verify the characteristics of the chicken they are purchasing.

Frequently asked questions
The colour of chicken meat depends on a variety of factors, including diet, breed, genetics, exercise, age, and nutrition. The yellow colour in chicken meat is caused by carotenoids in their feed, such as corn, fresh grass, or marigold flowers. While the white or pink colour is a result of feeding the chicken cereals such as wheat, soy, or sorghum.
Yellow chicken is associated with organic farming of slow-growing breeds, free-range chickens, or those with access to pasture and a varied diet. It is believed to have a stronger taste. White chicken, on the other hand, is typically from intensive farms and is lighter in colour due to its diet. It tends to have a more delicate flavour.
Marigolds are added to chicken feed as they improve meat quality and act as a natural pigment, enhancing the colour of the meat, skin, and egg yolks. They also provide good nutrition and help ward off insects.
No, the colour of the meat does not indicate fat content. Yellow chicken meat is not fattier than white chicken meat, despite the visual suggestion.
Yellow chicks are associated with Easter and are the result of genetics and selective breeding. The yellow colour comes from the yolk staining the white down feathers of future white chickens. This is not directly related to the yellow colour of chicken meat, which is influenced by factors such as diet and breed.
