What are some of the most common signs that a dove is ill?
Appearing fluffed up or droopy, having watery green droppings are some common signs of illness. Upon seeing a dove that looks and acts sick, isolate it and put it under a heat source (40 watt bulb). Heat is vital for a sick dove. If it is not eating, feed it hand-feeding formula (Exact Pretty Bird, etc.), and take it to an avian veterinarian.
