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.
