hey im a young bird mom i own a 2 year old budgie and something has been happening. Basically he is quieter and he has a weird liquid around his mouth that kinda smells like fish i clean it everyday with water but it doesnt go away and it seems like its bugging him a lot also idk he sleeps more and isnt as playful and i havent gone to the vet yet although ive noticed this for the past year. Yes i know its a long time but for the longest time i thought it was nothing but then i went to the vet 2 times and described to them but they arent as specialized so they gave me 2 different medications that i tried (in different times ofc) that didnt work and now idk what to do im going tomorrow to another vet to show them a pic aswell but thats the last vet i have in my town and idek if hes specialised. Please tell me what he has. I saw on the internet that he might have sometjing called “external parasites” (idk for sure cuz i speak another language) but i just wanna know if hes gonna be ok and what else i should do im so scared its eating me from the inside
