Recently obtained a breeding pair. Was told that they had coryza until I was leaving with them and just left anyway. They were treated with baytril and seem to be feeling MUCH better. They have been secluded to their own area coop/run... Wondering I they can infect my free ranging flock and birds in pens next to them? Most important question since they were going to be my incubator egg makers :/ can I hatch their eggs and the chicks be coryza free?
