Thank you for carrying. My crow have vomited that coin yesterday, im so glad.... Just wanted to tell that he's totally fine right now. No worriesWelcome to the Forums, Kuzu, but I'm sorry for the worrying circumstances!
I wish I could give you some advice but unfortunately I am at a loss. I'm not sure where exactly in the world you are located, but you may be able to find an avian vet using the link below, if not in your country then perhaps one who may be able to offer you a phone or video consultation?
Vets who look after farm animals or poultry may be able to assist, or perhaps a local zoo or animal or bird sanctuary?
Perhaps another member of our Forum may be able to offer you some better advice - I hope so! I wish you all the very best of luck 🙏
