Sorry about the emu Supreme. If you recall my boys ate from a box of zinc roofing screws last year and we took them to the vet. The x-rays showed numerous crews, bolts, nuts, washers, dog tags, etc. They were both fine but it was quite a scare. The vet is an avian vet who has raised emus for 30+ years. He said their GI tract is pretty much a straight shot and he wasn't worried about perforation.
On the other hand I took a sick chicken for euthanasia and necropsy last week and she had six screws in her gizzard and one that perforated. She also had an iron level of 9,000, 150 times normal. That was attributed to metal breakdown. Here is what the report said:
"Large amounts of macrophages loaded with a pigment consistent with hemosiderin were detected in small intestine and liver, probably hemoglobin break-down metabolites from chronic bleeding in to the gizzard in the proximal GI tract. Heavy metal screen of liver tissue detected extremely high levels of iron, this is probably a consequence of chronic iron release from the metallic foreign bodies ingested and the one embedded into the gizzard wall."
I know some pieces of hardware contain amounts of zinc that are toxic to animals even in small amounts. Hoping for a recovery for your emu. I don't know if any of this is relevant but I wanted to share it.
