I have one very tame hen, she is a big light sussex. She is like a dog. She loves being hugged and having her wattles stroked and her head tickled and happily falls asleep on you lap. Her comb is very red and she is healthy. When I picked her up today, she sat on my lap and fell asleep whil I stroked her, then I noticed the colour drain from her face. earlobes, wattles and some of her comb? does this happen when theyre relaxed I wonder? I doubt she's unhappy as shes obviously blissful when I do it. Anyone experienced this before?
