Hey, so this is our first time with chickens. They are about 11 weeks old now. When they were babies and under the lamp we handled them all the time, pet them, spent time with them, knowing we wanted to have "friendly" chickens. Now they are quite skittish, defiantly can't pick them up and when we do go to pet them they squak and jump away. Are they just being "teenagers"... Is there anything we can do to help them get over this. My 3 year old spends every moment she can with them. Brings them treats, talks to them... She just wants to pet them so badly and they just won't let her... And it's not just her. They are the same with me as well. I thought we did enough when they were super young to get them used to us. But since being outside it's just not the same! 
Any insight would be much appreciated.
