Make careful observations of exactly what you've noticed. If possible count how many breaths the bird takes a minute, plus take photographs of any abnormal droppings. This is because the bird will not behave the same at the vet clinic as she does at home, so this gives the vet vital information. Sick birds are easily chilled so keep the room warm. Ideally, locate a vet who specializes in birds and get yours seen as soon as possible.
