They say patience is a virtue. I'm really taking that to heart right now. I'm a first time mother to 18-almost nine week old feather babies, but I couldn't wait.... I wanted eggs, NOW! So I went to a sale last Saturday and bought 4 big gilrs, already laying. I didn't know that they should be quarentined(sorry about the spelling) so I put them in with my babies. After hearing one of the newby's sneezing, I realized she had a stuffy nose with dry crusted "boogers". I was cleaning that off when I smelled that odor of decaying flesh. I came inside and started looking on the web. That was when I figured that she probably had contagious coryza. I've done a lot or research on it lately and have gotten her somewhat away from the others. I have medicated her with the Tylan 50 for three days, and she seems to be getting better. Nasal discharge is looking better and not as much sneezing and coughing. While I was out with my babies this morning, I heard someone sneezing. I was hoping against hope that it was just pollen or dust, but when I found which one it was, it is one of by little RIR. She is breathing with her mouth open, sneezing, having labored breathing and wheezing with a few crackles. I immediately brought her in and gave her a dose of Tylan. She just pooped on me and it was just a small bit and liquid. Do you in your opinion think i've caught this in time, and should I put Terramycin or some other antibiotic in their water for the rest of them? I'm afraid by now, they have all been exposed.... Any suggestions?????
