I wouldn,t waist time and money trying to find out what is wrong with a sick youngster, happy to know it will never be a successfull racer. If all birds were to catch whatever it was, I,m afraid I would act no differently, even if it meant starting all over again, with the symptoms given, racers or stock would be of no use to me. As I stated previously, this may sound harsh, but this method has proved to work for me, as I have never experienced illness passing on to others, as I try to illiminate the source straight away. Since I have adopted this approach.
