Lorikeet vomiting all food for almost 2 weeks, no real vet access, desperate for advise
I have a ~6-7 year old coconut lorikeet who has been sick for almost 2 weeks now with vomiting. Details:
Started after he was given french fries (a family member has a history of giving inappropriate food like egg and fried/oily food).
Diet his whole life has been limited: baby formula (rice/pumpkin) with honey, soaked toast, occasional fruit. Refuses lorikeet nectar/pellets.
This is vomiting, not regurgitation. It's not the controlled head-bobbing courtship behavior. It's true vomiting, and the episodes are usually long, around 20 minutes. During this, he would vomit on empty stomach. More recently it has shifted to immediate vomiting right after eating, every time. He's hungry and wants to eat but can't keep anything down.
Weight: was 148g, now 135g (148>139>140>142>135)and dropping.
He also does a cough/head-shake "clearing" motion that sometimes leads to vomiting.
Started compulsively chewing wood right when the illness began. This is not normal beak sharpening. He bites an actual piece off and then chews it until it's almost gone. We've removed all wood for several days now with no change.
He is still playing, active, flying, vocalizing and seeking his person, but he gets tired earlier than he used to, and each day he is visibly getting weaker.
Vet situation: There is only ONE avian vet in the entire country. She refuses X-rays and bloodwork (says unnecessary/stressful). Her only treatment is a once-daily injected antibiotic (enrofloxacin/Baytril). He improved on the injections but relapsed when we switched to oral (he refuses all food when medication is mixed in). No emergency vets, no other avian vets, no diagnostics available. Neighbouring countries also have no avian vets or extremely limited access, and travel isn't possible.
I'm not looking for a diagnosis from strangers. I just need advice or any experience from people who've dealt with something similar, especially under limited vet access. Any ideas on getting nutrition into a bird that vomits everything, managing this without diagnostics, or anything that helped your bird, would mean a lot. He's still fighting and I'm trying everything I can within these constraints.
