Chinchilla ate aluminum tube

Hi everyone, so i have a lacto vite paste which i feed my chinchillas sometimes which's tube is aluminum. one of them chewed part of the tube and ate it. I was very concern and have kept close attention on her to make sure she's doing well. She seems to poop less and when she does, I found a little piece of aluminum wrapped inside her poop and I assume there's more in her system.The poop seemed to be normal size and shape. I've called a vet and going to take her in the day after tomorrow; however i would like to know if she's going to be okay and what I can do now before the checkup. Since I found this little piece does it mean she's able to pass the tube naturally? Thanks a lot for your help!
