She'll be fine. Unless you just have one ear or don't mind the journey your earplug is going to take i'd get myself a new pair.

Ok.thank you everyone for your great responses to eating the plastic. Our 6 month old adventurous girl ran into the laundry room and ate a foam earplug. I can't find anywhere on line about what to do when a chicken eats an earplug. There are tons of articles when a dog or child eats one. Crossing fingers and hoping that she doesn't die while we are on vacation! I have tears on my eyes from laughing at everyone else's similar issues. Thank you!
