What is wrong with my dog? She is pooping out bbs. My dog ate some of my bbs for my bb gun.?

My dog ate some of my bbs for my bb gun. I left some of my bbs in my basements and she found it and ate it. Then that day she pooped out bbs. Is it bad for her. She poops every two hours. She sometimes has a hard time to poop and it takes too long for her to poop. Is the bbs the cause of my problem?
