Rooster Hanging His Head

For the past few weeks my Rooster has been acting odd. When it stands or sits its head and neck will slowly fall to the ground. He will then just stand there with his head on the ground and rest of his body in the air.
Also for about a year he has been standing around with is head tucked into his neck, I didn't think anything of it until now that he has been doing this. I'm not sure if its a common thing with old age or some kind of sickness.
