Does this chicken comb seem a bit purple?

[Jimmyjonee]

Hi I’ve been noticing my that my chickens comb looks a bit darker in colour compared to her friends. Is this something I need to worry about or is this normal? The one on the right is her

She'll be right. It just differs from chicken to chicken.

It doesn't really look that purple to me, but it's difficult to tell based on a photo. The software on phones these days changes color hues all the time.

Combs that turn blue/purple can signify a lack of oxygen. This could, in theory, be a sign of Fowl Cholera, but you should quickly see other signs in the acute form. Do you notice any of the other symptoms of cholera, like diarrhea?

Lack of oxygen can also be due to anemia, a lack of red blood cells to carry the oxygen around. Did she eat something special? Some food like onions are toxic for chickens and sulfoxides can kill red blood cells. Do you feed them with table scraps?
