I think your thread should come up with some good questions and will be helpfull to new comers to the sport , after all the amout of different preperations and so called remidies it's a mine field of different products , some work some dont , but im sure alot of money is waisted on most things that simply do dont anything. I suppose some fanciers are lucky how they get there start and a good mentor who can save the new comers from the many pitfalls that can happen is a good thing , i was luck enough to have this and was shown the route to a good avian vet , which is half the battle, unhealthy birds cant be made fit via training and a over treated bird will not make a loft full of healthy ones , its all about ballance and to treat when not nessersary when a bird is not ailing is a waiste of money surely a once a month test is cheaper than treating for several things when you cant be sure your treating for the right thing in the first place. However canker is better controled once a month , rather than treated for because by the time its shows its usualy too late.
