I have an Australorp 1 1/2 old. She came down with a respiratory illness and is now in isolation. She was lethargic, breathing heavily, lightly wheezing with not much of an appetite. Took her to vet and was given a steroid shot, pills and Tylan. I suggested the Tylan to use as a preemptive for the rest of the flock since they've been exposed (I'm throwing out all eggs) though none are showing signs. Put her in isolation and this morning she had a little more perk to her, she still has labored breathing and prefers to sit. it's a nice day out so I opened the window and she called back to her buddies in the yard, her little voice is so raspy and squeaky right now. She is eating and drinking. Mixing the correct dosage of Tylan to water and soaking bits of bread to give her. Pill time is ridiculous, have to hide that in bread too and watch her closely. So here comes the question..... The vet said I'd know within 48 hours if she is gonna make it, if she doesn't I'm certainly taking her for a necropsy (hate to think about it though) I have 10 days left of medication if she makes it and seems 100% do I reintroduce her to the flock? When should I if I should? Are all my other birds carriers now too since exposed? They free range and have all grown up together, so could they all be carriers and she is just weak? Sorry for all the ????s I've just heard so many horror stories. Okay that's it for now. Looked around online but just couldn't seem to get a straight answer. Please help.
