Perhaps you can get over the "morality" of "affection?" Chickens are food and safety motivated, period. That's not a moral failing, it's evolution and their prey status. Once they know you well enough to not fear you (through treats and gentle, consistent behavior on your part) they will be comfortable around you, but always looking for food--because they are chickens. Each animal responds to what their natural needs are. Social animals respond to company, touch, and of course, food. Non-social species need food and proximity but no touching unless they instigate it. Your chickens will, once they are comfortable with you, recognize you as a big protector--you are closer to the hawks than they are. That often makes them want to be around you. Respect for their capabilities and needs, over one's own, is was makes relationships with other species rewarding. Be grateful for the privilege of interaction, and leave your own ego (not a criticism) out of it, and you'll experience great reward with every species. They shouldn't have to act like humans to be valued.After you've bonded over treats, what happens if you ever go in and you don't have treats? Do they still want to hang out with you, or do they only like you when you bring them food? It always annoyed me when we were growing up how my little sister always bribed the animals with food and they loved her, when I was trying to win them over with kindness, grooming, playing and other more social (and more honest, in my eyes, haha) methods, and it seemed so unfair, that I have been forever biased against treats, haha. Those were mostly mammals though. I know chickens aren't dogs/cats/goats/smart mammals that bond socially to humans, but is it possible to bond with a chicken and still be their friend even after you have to cap the treat supply for the day and you just want to hang out?
