I have been trying to battle some type of respiratory infection for over a month now. Symptoms were minor- only a couple of the birds ever showed symptoms (sneezing, minimal rattle at night). Now this morning I just got ahold of a hen whose crop looked suspiciously large for that time of morning. Sure enough in the scuffle to grab her she vomited this thick yellowish-white fluid and slung the stink all over my pajamas. (Should have known I couldn't have coffee on the porch without taking on a chicken task!) Anyway, it feels like a big water balloon. I tried to vomit her and got a little more out, but she is still pretty full. In the process of holding her, I noticed little bubbles in the corners of both eyes. I am thinking that for the respiratory I will finally have to break down and use antibiotics. How can I treat the sour crop without vomiting her? The responses I have found online all seem to be treating impacted crop, not sour crop. Also, should I give her the antibiotics at the same time? Or should I treat one and then the other? I know sour crop is basically a yeast infection (I think). Will antibiotics help sour crop if I have to give them for respiratory anyway? Another note- all chickens (even the one I pulled for sour crop) are acting normal and active and like nothing is wrong. Thanks!
