okay my budgie likes shiny things and it pecked on my necklace and pendant for a bit and I've noticed one of the small diamonds on my pendant have disappeared. I don't know If he actually pecked it out of its spot and spat it out or swallowed it. If it swalled it would it die??

I would think if he was strong enough to peck the diamond out of it's setting and if it is small enough, it will just pass through his system. Keep watching and good luck.

It's pretty small. Smaller than a millet seed. Thanks for replying I am SO worried. I hope it doesn't kill him.. If he did swallow it that is...I hope he didn't...and if he does poop it out I probably won't even notice since it's so small. Anyway thanks for the reassurance

follow him about with a magnifying glass the next day or two

I agree with Phoebe, if its small enough it should pass through his relatively easy

I hope so....and thanks for the replies! Though, I'm not going to hunt through all his poop to find it!
