I have a 6 year old cockatiel named Pip. My birthday was a month ago, and my friend got me some hoop earrings; I knew that cockatiels could get heavy metal poisoning so I asked them what the earrings were made out of and they said stainless steel. I'd put Pip on my shoulder and he would nibble on my earrings time to time. Today however, I noticed how he started chewing and something flaked off. I immediately touched his beak and made sure he didn't swallow anything but he started grinding his beak meaning he definitely swallowed some particles. Concerned, I asked my friend where they bought the earrings and they said Brandy Melville, which has earrings that are relatively cheap priced. I check the website and the materials says "lead, nickel, cadium component". I'm super worried about Pip now as he's been chewing on the earrings for a month now. I haven't seen any symptoms but I noticed that he's been closing his eyes a lot more and seems sleepy? He naps throughout the day so I wasn't too worried but I've been keeping my eye on him since and now I'm worried that it's a symptom of heavy metal poisoning. Does Pip have heavy metal poisoning and if so, what can I do at the moment?
