roosters faces & combs changes from pale pink to dark red...

[stevin]

is this normal...? has anyone ever seen this?
one minute their faces will be a pale pink, maybe not all but most of them. then in a blink of an eye their faces & combs will turn blood red.
sometimes i've notice this happen when my dog comes around the run or when i'm tossing in treats or even when theres a loud noise that startles them. does the color of their faces and combs reflect their mood? this also happens to the pullets but it's just not as noticable.

Very normal. When we humans blush, it's just a rush of adrenaline, causing increased blood flow, thus, the red face. When a chicken gets startled or exited, they also have an adrenaline rush, and it can be seen on their exposed skin. Some parts get more red than others. I have a turkin hen who's neck and head area turns red whenever you pick her up or she gets exited.
