My blue gold Macaw age about 6 month, not sure about the sex, weight 885g. Just noticed for couple of days lost appetite, not eating much. stool don't look any different to me, not runny, dark green small white edge.

all active want's to stay out of the cage all day, will not go in to eat. just sits on top of the cage.

Have given various food fruit, seeds, boiled pasta, nuts, not sure what else I can try.
