lots of points here owen 1st these fanciers are the lifes blood of the sport they far outnumber the out an out winners they are there to enjoy their pigeons and winning a card is a bonus without them the sport is dead with that in mind they are not interested in using ets ,why would they they are there for the fun of it which a lot of us have seemed to forgotten about in the quest to win at all costs so in the end who are the so called fools as to looking after their birds properly look at it this way- if the birds hit trouble the heavily fed birds have the back up energy to come home as the ones sent empty will struggle ok they wont win short races, if healthy and fit should come home though
