Hello, my pigeon will throw up seeds intermittently throughout the day. I took him to a vet and they gave him bactrim, nystatin, and benebac. His poops are now darkish green with yellow urates. The vet said hes perfectly healthy but the xrays showed 12 opague objects in his gizzard. No gram stain was done and they want to recheck him in a week. They claim he didnt throw up any seeds while there but i think thats just because he didnt like their feed and wasnt eating or doing so when no one looked. Any tips on what could be going on? Hes constantly cleaning himself, more than usual. Thanks in advance!
