Can you leave cooked chicken out all?

No.

Cooked chicken should not be left out at room temperature for more than two hours. After that, it should be refrigerated or frozen to prevent the growth of bacteria.

Bacteria can grow rapidly on cooked chicken at room temperature, which can cause food poisoning. Symptoms of food poisoning can include nausea, vomiting, diarrhea, and abdominal pain. In some cases, food poisoning can be fatal.

To avoid food poisoning, it is important to refrigerate or freeze cooked chicken as soon as possible after it has been cooked. Cooked chicken can be stored in the refrigerator for up to three days or in the freezer for up to six months.
