I have a White D'uccle Bantam hen who is about a year old now. She is at the bottom of the pecking order in my flock. Every time I try picking her up, she will try to bite my hand, but if I'm careful enough, I can get her without being pecked. When I hold her, I can feel her heart beating really fast and I'm afraid she might have a heart attack or something else along those lines. Should I stop picking her up?
