I meant a chicken isn't going to die from starvation
over night or because you with hold snacks... when they are acting picky about the feed you are offering them. If a chicken is hungry... it eats when food is available.. and for the OP that maybe there is more going on and further research into WHY said chicken is SUDDENLY not eating.
What I meant is that the chicken not eating is a symptom of something else and the OP should probably not worry so much about getting feed in and more so about hydration and monitoring the situation for more clues like droppings and such.
It was meant as a statement relevant to the discussion at hand and not a blanket statement that chickens "can't" die from starvation. Of course they can. Sorry for any confusion.
