Welcome! I am Dr. Altman, a licensed veterinarian and I am happy to answer your questions.
Luckily bird bones are quite shallow and will be broken down in the stomach
Unfortunately vomiting is contraindicated at this point (the shards can do more harm than good to the esophagus) so give her a few pieces of bread, wait a few hours, then repeat and increase her walks for 24-48 hours to increase her motility and push the pieces through
They should pass within this period of time
If she has any vomiting, reduced appetite, lethargy then I would contact your veterinarian but at this point it is a matter of them passing through her gi tract to the other side. Most cases will pass without incident
Please let me know if this information makes sense and any additional questions I can assist with today
Great! Can I assist with any other questions today?
