Facial massages! Oh yes! Even my bad-tempered GLW Irene grudgingly endures having her cheeks and ears stroked. My other somewhat standoffish hen, Geobett, a Speckled Sussex, will shut her eyes and go completely limp. Even the babies, especially Strawberry the Cream Legbar, adores having my fat, swollen finger stroke her tiny face and she always falls asleep during it. I would say that, besides food, facial massages are the most corrupting exercise you can engage in to endear yourself to your chickens.
