I am a chicken newbie and recently we acquired 2 five week old buff orpingtons. I have tried to feed them some treats and they have turned their beaks up at everything. They won't touch yogurt, greens, cheese, in fact the only thing they will eat are ants and their chick feed. They also are very scared of me and my husband. I am beginning to wonder if they had any human contact at all before we picked them up. How do we help them get used to us? Is it to late?
