Light Brahma face color changes quickly and often

[Jeffross1968]

We have 14 birds, one of which is a 6 month old, yet to lay light Brahma. We have noticed with her, but not our others, that her face can go from bright red to almost completely lacking of color in seconds, and it does this often. We'll go out and sit with some treats...while eating the treats she'll get bright red. Afterward, she'll jump up on one of our laps, and after a few seconds of squatting and relaxing there, the color just drains from her face. Is this normal?

My light brahma cockerel does the same. He goes all pale on hi face when I hold him and have him sit on my lap. Even when I'm petting him and he's falling asleep his faces goes pale. Maybe it's normal, but who knows
