What is the ruling regarding a chicken slaughtered by a man, from which approximately a cup of blood flowed, and it flapped its wing once then put it down; is it considered carrion?

If a chicken is slaughtered according to the lawful method, the movement or position of its wing indicates that there is life in it, even if it was sick. The minimum signs of life that indicate a valid slaughter are the movement of the eye, tail, or leg, or the gurgling of breath in the throat. Therefore, the slaughter of that chicken is valid if it was done in the prescribed manner. The lack of visible movement from it might be due to blood depletion.
