I have had my 6 pullets and 1 cockerel for 2 months now. They were super skittish when I first got them, and I was not able to get near enough to any of them to pat them.
Every day I take my bucket of treats down to the run, sit on a milk crate in the middle of the yard and throw treats. I am usually there for at least an hour. They are at the stage now (2 months later) where they will take bread from my hand, and ONE will let me pat her when she walks past!
At night, when I lock them in the coop and they are already on the roost, I am able to pat them. They are half asleep then and don't really notice me! I do so just for a minute, talking reassuringly the whole time and telling them they are good girls and boys - a quick pat each so as not to frighten them!
It really does take time. They are naturally wary, but you can earn their trust. One, slow step at a time!
