So, I took him to get a second opinion today. Here’s what they said
Injury: it’s probably infected and has led to various infection through his body. How? I don’t know. I’d been using the vetrycin every day for the past week. She said it was surface level damage and that there’s every chance it’ll fix itself in a few sheds, but also that he’s terribly sick. They sent me home with several syringes of antibiotics to administer and said he needs to be quarantined
Feeding: he’s been on hunger strike since March 3rd, I’ve been offering him food every/other week and he’s shown interest but hasn’t eaten. Vet said he’s too skinny (did NOT say he was anorexic and never eating again, like prior vet) and said I should try to feed him mice, chicks, or quails. They had to force feed him formula at the vet today. She said him hunger striking is really really bad but also that it’s completely normal and out of my hands but ALSO something to feel terribly afraid for
TLDR: things are looking bad. I feel horrible and like I’ve led him to die of some completely preventable disease. I don’t know. There’s the update. I don’t know.
