Well, symptoms can sound the same and one person's birds die from a certain treatment and another's get well. That's because diseases may have similiar symptoms but the treatments could be very different. You really can't tell that so & so's birds had the same disease or infection, or virus unless a vet and or lab results tell you so. It may be cheaper to try stuff at home but, if it ends up wiping out your flock - you may have to spend plenty replacing them. This is just my viewpoint but, whenever I've tried to skimp on expenses (I'm on very fixed income) and nursed them myself and lost them - then got autopsies, I'd find out they could have been saved if they had the right medicine.
