My whole flock of Bielefelder's are like that, including the rooster. One of the hen's won't move until I pet her on the back.I am convinced pullets ‘talk’ (or talk back) to me. Two of my bielefelders, Livvy and Sweets, follow me whenever I’m out and about. Sweets gives a very cute quiet chirping and will answer when I talk to her. She will jump to a perch to get closer and look me in the eye as we ‘talk’. She is like a dog, always near. Livvy is much louder with a long crescendo rapsy rrruuuupp rruup rup sound…actually several birds do that, but she’s another shadow.
I have one light brahma pullet that growls! I often retort back with ‘go lay an egg grumpy’
and 
It's enough that she irritates the rest of the flock at times, and they'll start pecking her to shut her up.
