I was wondering if I could get some advice. As a bit of history - I bought four new hens about a month ago. They went through quarantine fine so I integrated them with the flock. Almost immediately, one started sniffling. In my naivety I didn't check it right away and let her run with the others for a couple of days before I thought 'I must look that up online'. Then, to my horror, mycoplasma reared its head and though I isolated her, many others have also become snuffly. All are still eating and drinking, and to look briefly at the flock, you wouldn't know anything's wrong. But, eggs have decreased, I can notice some lethargy and both my roosters have had bubbles in their eyes - no hens have. Some of my hens sneeze, have some snot or have rattling breath. All myco symptoms, right?! So, I had the first hen test at the vets - both the fecal and throat swab came back negative for myco but positive for e. coli, staph and acinetobacter. I've got them on Tylan which will kill off the first two apparently, but they may need something stronger for the acineto. Anyway....have I got myco and the test missed it? Or can these other infections show themselves with similar symptoms? I was SO relieved when it came back myco negative but I'm not 100% trusting having read up on it and seen my hens.
