I am really sorry about Stevie, Guy. I know you have tried your best.
I agree that you MUST get your temps straightened out. They really can't digest well without proper basking temps, and dehydrate and become impacted without a cool down area.
I also agree that a fecal is definitely warranted.
Do you keep your collareds on sand? If so, please consider taking them OFF of it ASAP at least until the digestion issues are resolved.
