First of all I was stupid for not quarantining 2 hens for 30 days. They looked very healthy, I had no illness in my flock so I only kept them apart a few days. My very big BAD! I bought them at a flea market from a man who raised them. Really don't think they were sick but suspect they picked up a bug from other birds nearby. One of the hens looked depressed (lethargy), the next day she had rattling resp. I thought she picked up something in my pen that my chickes were resistant to. WRONG. Next day my roo was obviously very sick as was this hen. Wheezing, coughing, lethargy; my roo has even quit crowing. Of course by then the whole flock was getting sick. That was several days ago and although they still are sick no one has died. What do I need to do for future flock management (less than 10 birds to raise eggs and for meat)? Do I need to cull them all? Can I eat their eggs? What about the eggs I put in the bator some of which were laid the day before they showed symptoms? What about future chickens? Please help me figure out what to do? I promise to never fail to quarantine a bird in the future; in fact I doubt I will ever buy another bird. I just thought Rocky really needed some Barred ladies that looked like him.
