hmm, id go to the point many successful fanciers, that i know dont have a health programme by treating with antibiotics, but have a health programme involving preventatives, and i should add natural preventatives for cocci, canker, worms ect, and they will only treat when something is wrong. But they use plenty of vitamins, minerals ect if you understand what i mean, just like a proffessional athlete, they will take vitamins and minerals, to enhance there state of fitness, but they wouldnt take an antibiotic, unless they was ill, they like us wouldnt take an antibiotic, if they didnt have an illness as a preventative. But with there natural products vitamins, and minerals they take throughout there feeding system it helps to build a barrier against the common illness's.
