Is it normal for the comb and facial skin on chickens to go pale when they relax? I have one girl who's decided she loves getting petted, and she will jump up and lay down on me. As she relaxes and settles in, her skin goes from red to pale. She doesn't seem in any distress. No worms, lice or anything. She just lays there talking to me as I pet her. After she's jumps down, the color comes back. Is it just relaxation? She's only one of two that snuggle like that, and the other is a silkie so I can't see any color changing on her.
