Water, feed and a handful of grit and my birds are looking perfect. Anyone that sees them comment on their condition. Ive won in every show I entered this year lol. Ill give them treatment ONLY if and when they need it, I take samples several times through the year and unless they desperately need treatment, I leave them and let them get on with it. Whats wrong with most fanciers is they are frightened to NOT give them anything, try it and see how much money your wasting. Believe me, ive spent ( wasted ) plenty of money on all the fads and fancy potions and was convinced that they were responsible for my success. However, after a long discussion with a top fancier I was persuaded to give them nothing but the basics and to my surprise the pigeons flew as well, if not better. You wouldn't take medication for a headache unless you had a headache and this applies to treating pigeons also . Im gradually going back to the way it used to be, the main treatment for a sick pigeon is the spade. Im also of the opinion that your really top pigeons seldom get anything up with them that they cant shrug off themselves.
