I have a 10-month old silkie pullet who has suddenly become very sick, and I'm having a hard time deciding whether or not it is time to let go. About three weeks ago we noticed that she was dragging one of her wings. Since she was otherwise healthy and did not seem to be in pain, we splinted the wing and she seemed to fully recover. However, two days ago she started acting lethargic, and then quickly went downhill. We isolated her from the rest of the flock and tried treating for lice and mites because we noticed signs of an infestation, but there was no improvement. She ate a little yesterday, mostly treats, but hasn't taken anything today. I've tried feeding her water and electrolytes with an eye dropper, but she seems to hate it and tried to shake me off. She barely moves, just stands there puffed up and looking miserable, and her poop is bright green. I spoke to a vet this morning and she offered to see her, but told us it would be a waste of money because in her experience once birds go downhill they do not recover. She offered to euthanize the bird and send her for an autopsy instead. I am really struggling with this decision, because Daisy is a much-loved pet and I don't want to give up on her if there is any chance that she could pull through. Does anyone have any experience with chickens this sick recovering? Or am I being unrealistic? Thanks so much in advance!!
