Hi today I talked to a lady from craigslist she was very nice and has a few rare breeds. I wanted to buy her sickie pullet two easter egger's and some chicks. But then she told me she may have possibly had cocksy(not his u spell it...) now im skeptical. What does this disease do and how can I prevent it from getting in my flock or should I just straight up not buy from her and stick to buying hatchery birds or hatching my own?
