I go to the coop several times a day and hand feed my 4 week old chicks.  At least a 1/2 dozen of the 23 chicks come running as soon as I open the door.  As I'm feeding, several others will come and jump on my arm and actually squat down and roost while I'm feeding the others.  As a result, I'm able to pick up most of the chicks relatively easily to move them when necessary.  I think, in the long run, it will be beneficial I have taken the extra effort to acclimate them to me.
