Is apple cider vinegar safe for my parakeet's vomiting and digestion?

Thanks for reaching out about Bluey and including photos. The cause of the regurgitation needs to be discovered. Primary reasons that are likely are heavy metal toxicity, ingested foreign bodies, mega-bacteria and more. A veterinary visit for radiographs and blood work is recommended. Heavy metal should show up well on radiographs. Providing heat support in the 80-85 F range can give some aid. Good luck.

Thanks for including the picture of Kiwi. It seems like Kiwi is regurgitating. Parrots can regurgitated for multiple reasons: food sharing, stress, eating something noxious, ingestion of something toxic or due to infectious or metabolic illness (kidney, liver, etc.). With food sharing, they rarely shake their head and spray it everywhere. One of the other more common causes is eating items with lead or zinc, two soft metals, that affect the vomit center to cause the regurgitation. You'll have to investigate the environment and search for anything Kiwi might be chewing on. If you think that is the case, a visit to the veterinarian should provide a means of confirmation (radiographs) and then the treatment has a fairly good prognosis as long as it is caught fairly early. Providing heat support for an environment around 85-90 degrees will help to stimulate his immune system. But if he continues to regurgitate or become lethargic or anorectic, you need to visit your local avian veterinarian.

Thanks for reaching out about Bulbul. Is this bird only 8 days old? Regurgitation is not normal, but could be due to over-feeding, a crop infection or impaction, sub-optimal husbandry, viral diseases, and other. Older birds are more likely to have eaten a foreign body, something toxic, metabolic diseases, and others. If continues to regurgitate, a veterinary visit is recommended. Good luck.

Thanks for reaching out about Pudgie. Regurgitation can be behavioral but also possible illness such as metabolic disorders (liver, renal), toxicities (zinc, lead, plants, etc.), crop infections or impactions and more. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Good luck.

Thanks for reaching out about Zinnia. Regurgitation can be caused by inhaled or ingested toxins (plants, paint, zinc, lead, etc.), metabolic problems (liver or kidney disease), infectious agents, gastrointestinal foreign bodies, just to name a few. A veterinary visit is recommended soon as when they are regurgitating, they are not digesting food. Good luck.

Thanks for reaching out about Monu and including photos. Regurgitation can be caused by many thing such as ingestion of foreign material (plastic, fabric, wood, etc), toxic ingestion (lead, zinc,plants), metabolic disorders (liver, kidney), infections and several viral diseases. Each of these have different means of diagnosis and possible treatments, therefore a veterinary visit is recommended. Chronic regurgitation can lead to dehydration, electrolyte imbalances, malnutrition, and more, making a veterinary visit even more expedient. Try offering small amounts of food and water, more frequently to decrease possibility of regurgitation. Good luck.

Thanks for reaching out about Fandogh and including images. Anti-emetic (anti-vomiting) medications can be given by injection, so might reduce/stop regurgitation, that can then allow oral medications to be given. Subcutaneous fluids might have to be given to maintain hydration. Were follow up radiographs taken after the initial ones? A gastrointestinal foreign body must still be considered. Good luck.
