OK is it true that hens curl their head back over their shoulder or under their wing to sleep and roos keep their head up/out? DH si driving me nuts with this whole "lets sit here EVERY NIGHT and figure out who is a girl and who is a boy out of the 100 roo's we ordered.... we have about 5 that sleep with their heads curled back over their shoulders and everyone else keeps it out front or hanging down to sleep. I told him I would ask.
