Holes in Poop

My chinchilla has always had a sensitive stomach. so he's had issues with feces that never was indicative of a larger issue (parasites of enteritis or anything...) A week ago, he actually got into a wire and chewed it up. it was the wire to a digital thermostat i kept near his cage (my mom was looking after him and let it get too close accidentally. it's made of plastic outside and copperwire. which i know he ingested.). i took him to the nonspecialist emergency and they said the only thing we can do is wait it out. which pissed me off to no end but it was 2 am in the morning and the closest specialist was 2 hours away. i was manic and so upset. i cried that night and honestly thought he was going to die. he seemed to show signs of bloat for that night and i saw copperwire from the thermostat being passed in softer than usual and lighter poop. but pretty soon it became normal relative poop to what he had so i just assumed the worst is over and he passed all that he had ingested.



now in the last week, in the periods between dawn and morning he will definitely have tiny tiny poops that isn't constipated and hard but still soft--which is worrisome. also i've broken open some of the larger better poops (which he passes during the nightime and twilight hours) and they have had some tiny holes in them. should i take him to a specialist or do you guys think he should be fine and that the holes will pass? i don't know what i'm dealing with but i would like some basis to go off of. is this impaction or infection??? should i get an ultrasound or x-ray? or test the poops or both?
