If you spend lots of time with your chickens then they will love to be picked up and cuddled.
They will enjoy falling asleep in your arms, watching TV on your lap, resting on your knee and burrying their faces in your hair or under your hood. My chickens have even groomed me by rubbing their beaks across my clothes and through my hair!!
If you are sat in the garden and a hen walks up, jumps onto your lap, settles down and falls contentedly asleep, then you know you have been accepted in the flock!
Chickens can learn their own names if repeated when you are interacting with them, for instance when you are stroking or carrying them. If a hens name is said enough it will make a connection between its name and itself. This can come in incredibly useful. My chicken Milly flew over my neighbour's wall the other day (she escaped when the coop door was left open by accident). She was merrily scratting round their garden. My dad had tried to reach her, but couldn't. He was all for going round and knocking on my neighbour's door when I went and called her name. I said, "Milly, come here! Come here Milly!", and, from about ten feet away, she came running to the wall as fast as she could and squawked at me, just looking up. I thought at first she couldn't fly up because the wall is about five foot high. I was just getting ready to climb down when she flew up straight into my arms and cuddled me!!
