Why is my budgie's poop green and watery? Will Ronidazole help?

You need to tell us what the antibiotic you have. We cannot give you any advice without that information. You need to understand that not all antibiotics treat every kind of infection. We don't even have a diagnosis for Skye there is no way to know if it will even work.

Thanks for reaching out about Meow. Possibly this is not an infectious problem, so antibiotics and anti-fungal might not help. With an all seed or heavy seed diet, fatty liver disease is possible which will not respond to the medications. Increasing protein and vitamins in the diet could help, as could an increase in dietary fiber. An avian veterinary visit is still recommended. Good luck.

Looser stools can be caused by a number of things. If you've recently given Sky a bunch of snacks (such as fruits and veggies) or changed her diet, this can cause temporary stool color changes or moist stool. Removing any extra treats and letting her adjust to her new diet for a few days may help. If she has differently colored pellets in her food, this may also cause color changes to the stool as well. Other causes can include parasites, GI upset, illness, nutritional issues, metabolic issues, etc. If she didn't have a diet change or any snacks, or is showing other signs of illness in addition to the loose stool/color change (you mentioned she is less active), then having her examined by a vet is best. They can treat her for parasites and help rule out any more serious underlying conditions that may require treatment.

Diet changes can affect the stool, and if you're feeding any extras in addition to the diet change, this could be causing the change you are seeing. It is also possible that his current diet is causing some minor GI upset if it changes immediately after eating and then returns to normal. Other issues such as internal parasites can also cause stool changes, so ruling out and treating for any parasites may be a good idea. Removing any extras such as fruit and veggies and providing only his balanced diet for a few days may also help him adjust and his stool return to normal. If the problem persists, or you see any other symptoms or changes such as reduced eating/drinking, lethargy, etc, then seeking vet care in person to rule out any more serious issues is best.

Thanks for reaching out about Susi and including photos. Other diseases can cause greenish stool, anything that affects liver function. AS you probably know, psittacosis is zoonotic. Veterinarians can sometimes have access to injectable doxycycline, since won't take orally. Gavage feeding the medications and food could also be beneficial and a veterinarian can assist with the technique. You might have to travel further is an avian veterinarian is not in your vicinity, as this bird sounds critical. Good luck.

Thanks for reaching out about Pipo and including photos. The greenish stool is probably due to poor nutrition and possible liver disease. A comprehensive avian profile should be performed to analyze the white blood count and organ functions. Also a test for Psittacine Beak and Feather Disease is highly recommended. This is a virus, non-treatable, contagious to other birds. You need to get better nutrition into him, as apples are fiber and sugar. There are many commercially available baby bird feeding formulas, but as your veterinarian. Good luck.

Thanks for reaching out about Popo and including photos. This sounds as if she is not eating (therefore no feces) and drinking more water (more urine). This is called polyuria. Kidney or liver problems, ingested foreign bodies, pain, hormonal problems are just a few of the possibilities. A veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Providing heat support in the 80-85 F range can give some comfort. Not sure which antibiotic this is but unlikely this is caused by a gastrointestinal infection. Good luck.
