I just got 4 hens. Two 10 week old, an 11 week and a 14 week. They all seem to be afraid of me and don't seem very interested in the scratch or garden treAts I give them. They just stick to there all flock food. Will this just take time? Also any advise on raising my hens to be friendly and starting from 10-14weeks in age? What age do they start laying? I can't wait for our first egg!
