I have been reading a lot on here b/c we just got a pair of peafowl also and have never had them before. The breeder told us to keep them penned for a month before free-ranging. They are in the barn with our chickens, in a separate pen right now. After a month it will be mid December, it will be cold and I wondered if it would be ok to let them out, as I'm guessing they would not go too far anyway in the cold and possibly snow? Or should we keep them penned up longer? We can't keep them separated from the chickens forever, unfortunately...if I had known this would be a problem we probably wouldn't have gotten them. We will give our chooks aviacharge in the winter, is this ok to give the peafowl, also?
