I have a Black Copper Marans hen who is the first to greet me at the coop door, and the first to try and get under my feet wherever I walk, squatting until I pet her. As soon as I sit down she comes right over to get petted, she'll even jump into my lap and lay down. I have noticed that she will also nip or pull at any zippers/buttons/tabs on my clothing, which I know is normal (shiny things!). But she will also nip at my arm and legs on occasion, not enough to leave a mark, but enough to be annoying. I've been pecking her back (with two fingers together on her back, not any harder than she did to me) and it seems to help a little bit, she's certainly not afraid of me even after I do that. Is this normal behavior? I'm not invading her space (she comes right to me before doing it), she seems to be using it to get my attention, kind of like a puppy nips at things. Is gently pecking her back ok? I'm used the same technique on horses who nip and it seems to work, but is it ok for chickens? I know I'm not hurting her, but I do want to modify her behavior. She's one of the sweetest birds I have.
