Would that have shown up on a fecal test? Or only blood draw?Im Branton's Auntie now ! Quakers are my love, I have 4.
Definitely not something you did.
Excellent to catch a systematic illness as early as possible.
Chlamydia psittaci is real possibility its common. Its treatable and doxycline is the drug of choice for 45 days. It's treated for so long because it likes to go dormant and hide. Many parrots can have a chronic hidden form only to break with active infection years later.
Not that I can say from here what your birds has.. I'm just sharing from my experience.
If I hadn't recommended weight checks yet, let me so. Having a digital kitchen scale and weigh in grams your bird weekly and log, daily when health issues. This weight check can be a life saver , as most burds start dropping weight when any health issues. And weight checks let's you pick this up way before the " sick burd symptoms " because burds hide being sick. So when you have duck burd symptoms they are usually critically ill.
Extra warmth is very healing and supportive fir duck birds. I recommend radiant heat , never a heat lamp. I use sweeter heater, but many use the K&H cage warmer.
Burds also burn up 3x the calories when sick, so go ahead and have a millet spray available, offer a little warm cooked plain pasta, any foods they like within reason. Not sugary foods or fruits as digestive imbalance.
Little info on potential possible , could have bern exposed at pet store , at breeders, from other people who have parrots. Its just one of those things that's in parrot population. ( many birds never have symptoms, or have mild symptoms and recover, but young birds can become very sick and even die. ),
Chlamydophilosis, also called "psittacosis", chlamydiosis or "Parrot Fever", is a reasonably common disease of birds. It can occur in any bird but is especially common in cockatiels, Amazon parrots and budgerigars (often referred to incorrectly as parakeets.)vcahospitals.com
