The last batch of chicks I had in the spring was a mixed group of birds with friendliness varying along breed types. All were handled from young birds but they seem to go through a wild phase as they matured. The Australorps and Kraienkoppes were the worst.
Then something interesting happened.
We changed the housing arrangements to keep each hen with her own breed of rooster at night which requires us to pick up each bird at dusk. We were quiet, moved slowly and talked to each bird; stroking them a little on the sides of their heads around their ears to soothe them. As they calmed down after capture, they started to murmur back to us. In a few days the wildest hens were unruffled about being caught, allowing us to easily pick them up at dusk. During the day, we can't just pick up those particular birds as we can the Orpingtons and Sussex, but they aren't afraid of us and will eat from our hands with the others.
