I have 2 1/2 week old chicks, have gone out everyday to feed, water, spend time with them...I offer treats (mealworms, superworms, yogurt) but they still act scared to death of me! I call them when I go into the coop, they know I have treats, and act VERY curious but wont gather round me. Only the Barred Rock chicks have the nerve to take a worm from my hand, or crane their necks with curiosity when I hold a treat for them. I work during the day, so I'm not out there all day, but I try to spend about 45 minutes a night with the girls. Suggestions???
