How is Sunny today? I just read through this post and I'm sure you understand the implications of a bird passing black colored stools. You mentioned that Sunny has been eating normally yet since he passed the black colored stool he has only passed urine/uric acid and no solid droppings...Has he passed any solid brown or green droppings yet, like this morning? Or how about more black colored stool? Was that single black stool the only black stool he has passed? I hope you've got him at an avian vet now as you said you were going to do, and that you'll let us know what the avian vet did as far as tests he ran, and what he said the problem is, as well as any medications he prescribed...
I understand that your birds are having some separation anxiety and are calling to each other constantly, but please use some common sense here and keep Sunny isolated and all other birds you have in totally separate rooms from Sunny!!! You don't know what's wrong with him or whether or not he has a parasite or a bacterial or fungal infection, all of which would be very contagious to any other birds in the same room as him, especially if you put your other bird's cages next to Sunny's cage! Just because your other birds have yet to show any signs or symptoms of illness does not mean that they haven't contracted a parasite or an infection from Sunny, or thatthat's won't now that you put their cages back together in the same room (and right next to each other to boot)! Birds hide all signs and symptoms of illness and pain for as long as they possibly can, it's instinctual. By the time they actually show ANY signs of being ill they have actually been sick for quite some time, and this makes them much more difficult to treat because the infections or parasites have aggressively progressed in the meantime!
Please, separate all other birds from Sunny! He needs to be in a completely separate room from any and all other birds until he either has cultures, parasite checks, and a fecal smear done and they all come back negative, or if the avian vet diagnoses Sunny with a bacterial or fungal infection or with a parasitic infection and puts him on antibiotics, antifungals, antiparasitics, etc. he should be separated from any and all other birds (TOTALLY DIFFERENT ROOM!) until he finishes ALL of his medications and has a follow-up fecal smear, culture, etc. and it comes back negative! LET YOUR BIRDS SCREAM! LET THEM CONTACT CALL! IT'S BETTER THAN THEM ALL GETTING SICK!
I may sound forceful or harsh about separating your birds from Sunny until you absolutely know that he's 100% healthy and negative for infections and parasites, but you'll thank me if none of your other birds become sick...Or worse.
I find that a lot of people, in fact the majority of people who either bring home a new bird into their current flock, or people who have multiple birds in their home and one of their birds starts to show signs and symptoms of illness refuse to practice proper quarantining techniques! I have no idea why it's so difficult or such a big deal for people to separate a sick or POTENTIALLY SICK bird from all of their other birds, or why they just simply cannot wait 30 days to introduce a new bird they've brought home to their current birds, especially when it could very well mean losing ALL of their birds if they don't! It's a no-brainer, so what if they are contact calling each other all day long, wouldn't you rather they were screaming all day long than dead?
