Thank you,
@oldhenlikesdogs.
We suddenly lost our second gosling, Faye, after an apparent streak of improvement- she passed while outside, grazing. We corresponded with an avian veterinarian and brought her body in for a necropsy, later setting an appointment for the final remaining gosling.
The veterinarian combed through her autopsy and could not find any evidence of parasites or infection. He was stumped, and ultimately concluded that their ailments were either viral or genetic.
Meanwhile, we spoke with another bird expert, who ran an exotic bird sanctuary. Looking at the nutritional information of their chick starter, he believed that nutritional deficiencies were not the answer, but rather aspergillosis. I was hesitant to accept aspergillosis then -knowing how difficult and fatal it is- but am growing to accept it now. Our poor gosling, Iris, has since lost her voice, another symptom of brooder pneumonia. She, once again, can no longer walk.
We are going to contact the veterinarian, to ask whether any evidence of aspergillosis was present in the autopsy. Unfortunately, we have a compelling list of symptoms that all point to the disease.
From embryos, the goslings experienced respiratory distress, including nasal discharge, wheezing, rasping, and popping. Later, they lost use of their legs, characteristically favoring one leg while being unable to move the other. I have read that aspergillosis, in advanced stages, can cause neural symptoms and/or paralysis.
Towards the end, the goslings suddenly developed drooling behavior, tremors/shaking and severe lethargy. These symptoms usually manifested themselves abruptly, only hours before death.
When we received the eggs from
EBay, some were quite dirty. It's possible that the eggs were exposed to aspergillosis spores while in shipment or the nest/pasture. However, if my goslings do have aspergillosis, I suspect it's my fault. We hatched out a duck ten or so days before hatch, and I ignorantly thought that thoroughly cleaning the incubator would disrupt the incubation of the eggs, and cause them harm. I could not have guessed that the egg remnants could affect the growing embryos. I've paid the ultimate price for my inexperience, having lost most of my goslings, with little hope for recovery.
Our final gosling is faring well, but has lost her voice. She still cannot walk, and must be carried to her food/water. She's now eating Mazuri waterfowl starter feed, accompanied by grasses and the occasional leaves of romaine, kale, or swiss chard. We're doing our best to keep her exercised by bringing her to local lakes and ponds, and swimming in short intervals. Her appetite is good, but she's become depressed since losing her siblings. We keep her with us as much as possible but do not yet wish to get another goose, as we expect her illness to be fatal.
We're going to check in with the veterinarian, who I sincerely hope can dispute our theory. I'll continue to keep this thread posted, but thank you all for your support and guidance.
