I just bought two EE from a hatchery and they have been sneezing every so often. They are in quarantine untill I figure out if they are ill or not. Is there something that I should be looking for? I do not want to introduce any illness to my other birds. It is bad enough that the two wilsummers that I have turned out to be Roos! They are going to a rescue org later this afternoon. Thanks for your thoughts.
