The first thing you need to do is keep her warm. Move her to a safe, dimly lit, warm place to the extent of your abilities. While it's best to feed your budgies on a regular schedule, as you know, not feeding her one time would not be enough to make her malnourished. It appears that she must have been ill for some time and hiding it, as budgies naturally hide illnesses in the wild to avoid being picked off by predators. Therefore at this point now her illness is to the point where she can no longer hide it. Make sure she is drinking, you can giver her electrolyte solution as described below: Guardian Angel // Pedialyte // Pedialyte Recipe


The next thing you need to do is get her to a vet right away. There is no way for us or you to know what illness she has and there is no way to treat it at home. Therefore as soon as the vets are open tomorrow you must try to get her to an avian vet or she likely will not make it. Best wishes for little Dove.
