Do Chickens Go Grey With Age?

Chickens are among the most often kept domesticated birds due to their usefulness as both food sources & natural insect deterrents. White, black, red, blue, as well as every hue in between are just some of the varieties available. Some chicken keepers and fans may wonder if hens get grey as they age or if their feathers change its color through time. This article debunks several common misconceptions about the causes of feather color changes in chickens & provides some evidence for other hypotheses. 

Myth #1: Chickens Turn Grey as They Age

Like human hair or fur, it’s a prevalent belief that older hens eventually become grey. Some older chickens, particularly those of contrasting patterns like barred or laced feathers, may contribute to this belief since their feather colors appear more subdued or faded. The truth, however, is more nuanced than a straightforward greying procedure would seem. 

Fact #1: Feather Coloration is Determined by Genetics & Environmental Factors

The genetic & environmental factors that influence a chicken’s feather color include, but are not limited to: 

Pigments: Melanin, carotenes, & porphyrins are the three major pigments responsible for the coloring of feathers. Melanin is the pigment responsible for the appearance of black, brown, and gray, while carotenoids & porphyrins are responsible for the appearance of red, yellow, and orange. The synthesis & deposition of such pigments in distinct feather regions is regulated by different genes, leading to a wide range of coloration and patterning. 

Structural Feathers: The feather’s barbs, barbules, & hooks can reflect & refract light differently depending on their size, shape, & arrangement, giving the feather an iridescent, metallic, or matte appearance. White or silver feathers lack melanin but also have air-filled gaps that scatter light, which can make the underlying colours more visible. 

Hormones: Feather growth, colour, & quality can be influenced by hormones like testosterone, estrogen, & thyroid hormones. For instance, hypothyroidism can cause fragile or sparse feathers, and castration or low testosterone levels in male chickens might cause them to acquire more feminine or fading feather hues. 

Health and diet: Take care of the relationship between nutrition and health. The growth and color of a chicken’s feathers are susceptible to the availability & balance of nutrients, enzymes, & minerals in its food. Oversaturation or coloring of yellow and red feathers can be caused by excess carotenoids, and a shortage of proteins or amino acids can cause feather loss or bland colors. Feather quality & color can also be affected by things like illness, stress, and parasites. 

Consequently, the answer to the question of whether or not chickens age by going grey is contingent upon the interaction of various elements, rather than a clear yes or no.

Myth #2: All Chickens Change Feather Colors with Age

Another common misconception is that all chickens, regardless of breed, sex, or environment, will gradually lose or gain feather color as they age. This could be owing in part to the fact that, in the context of reproduction or genetic selection, some chicken breeds actually have genes which cause their feather colors to vary over time. 

Fact #2: Some Chickens Retain Their Feather Colors Throughout Their Lives

Nevertheless, not all chickens go through this process, and some may keep their vivid or distinctive colors even as they age. Several chicken breeds, such as Leghorns, White Rocks, as well as Rhode Island Reds, are known for having uniformly bright white or red feathers that don’t change much over time. Similarly, healthy, well-cared-for hens are more likely to keep their feather colors than their anxious, hungry, or ill counterparts. While it’s true that some hens’ feathers change color with age, it’s not a worldwide phenomenon and is affected by a number of circumstances. 

Black, brown, and grey hens, as well as those with carotenoid-based hues like red, yellow, & orange, may show more noticeable variations in feather color as they age. Its because melanin pigments, especially when exposed to sunshine as well as other environmental variables, tend to fade or lose intensity with time. However, genetics, diet, health, and environmental factors can greatly influence the extent and velocity of color changes in different chickens. 

Conclusion 

Some hens’ feathers may change color with age, but this is by no means universal and is affected by a number of variables. The genetic, environmental, and physiological factors that influence feather coloring in chickens make this an interesting and difficult issue. If you’re a poultry farmer, the backyard chicken keeper, or just a keen observer of nature, learning the truth behind the myths regarding chicken feather color changes will give you a newfound respect for these fascinating creatures.
