I was so stupid in bringing home a rooster...to think my beautiful girls needed a man was such a mistake! He doesn't show any sign of being ill, but evidently was a carrier of something! He has gotten a few of my girls very sick the last 4 days. They all have a cough, and some are worse with a horrible weezing, and slightly swollen face. I have them on Duramycin 10, and vitamins & electrolytes.... which are working very well. I actually thought I was going to lose a couple of them and didn't expect them to live through the night. This morning they are all thriving, still a cough, but faces look much better! There are 6 total with the rooster. I have debated the last 2 days in culling them. I just hate to think of them as being carriers of this, and then hearing it could flare up again if they have any stress at all, and then to have to go through this again would be so upsetting to me. I have some 9 week old orpingtons that I have in a separate pen on the other side of our yard, and they all are fine. I sit with them daily so am sure they did not pick any of this up... not even a cough or sneeze...they are perfect. Just needing a little advice, and reassurance of what I should do.
