I went out to take care of my 10 week old pullets this morning after a brief thunderstorm. It was their first experience with one although they have experienced both rain and snow. Coincidentally (or not) today was the first time I noticed that most of the naked skin on their faces (combs, wattles, around the eyes/ears) was pretty dark pink. Before it had been yellowish to very pale pink. Now I didn't suddenly have everyone turn cockerel on ne nor do I think 10 week olds are coming into lay, so...do they pink up like that if they're scared/stressed?
