Good one Lee, but my wife might wonder what's going on if I came back from the coop wearing lipstick! Actually, if their pens are kept reasonably clean I don't think there should be a problem. Chickens have never made me sick, although the summertime dust when I clean their pens sometimes does clog up my bronchial tubes. Yes, I know I should be wearing a mask, but they don't work well for me.
