Both sexes change color as they mature. Females are typically a
lighter color 'red' and both sexes can become a bleached out red
(caused by sun exposure and natural lightening) After molting both
sexes get 'new feathers' often making them appear to darken, or in
the case of males by age and maturity. As they mature the color of
a male Rhode Island Red will deepen to almost a mahogany color
while a female stays typically 'lighter'.

Do Rhode Island Red Chickens feathers change colour during their lives eg Pale to Dark?-Well, let me tell ya, Rhode Island Red Chickens' feathers can sometimes undergo color changes during their lives. But it's not a super common or drastic shift like going from pale to dark. Usually, their feathers might fade a little or get some minor variations as they age, but it's not a huge, obvious transformation. It kind of depends on a bunch of factors like their diet, environment, and overall health. So, it's not a definite yes or no, but more of a maybe with some conditions attached. Ya know what I mean?
