We got our three chicks at one week old, and have been trying very hard to hold them to get them used to us since the day we brought them home. We would pick them up and gently stroke them on the sides of their necks and cheeks. They seemed to have gotten more used to us as the weeks went on, but all of a sudden, at 3 1/2 weeks, they want nothing to do with us! When I pick them up, they squawk like they are being killed, try to fly out of my hands, and will not settle down to be gently stroked. The barred rock now tries to peck me when I pick her up. I do not think I am picking them up or holding them any differently, they are much bigger now, so a little harder to hold in your hands than before, but I would not think that would make so much of a difference. They are all three starting to feather out, with our welsummer having the most feathers, and the Ameraucana the fewest so far. Could that be it? It is making me not want to pick them up any more, since they seem to hate it so much! But, it is was my goal to have chickens that we could interact with, not just animals to ignore and collect eggs from. I am so frustrated!
