Thank you so much for your answer, Crowley is still having a hard time, poor little guy. I won't put rocks on the hides then. My bird poops so much I have no issue bringing in a sample. I'll probably have to do an emergency visit to the vet tomorrow if Crowley isn't doing any better by then. At least I know people who live near the vet but it's 3 and a half hours away for me so today isn't an option.
