Well i have been racing for 4 years, this is my 5th, and i have never treated during racing before, and my results are not the best. Take last year, i won first 2 old bird races, then was nigh on last every week. So after taking dome good advice off people on here, im trying a different approach this year, As some of the birds i see on the fed transporter, well!!!. I said to 1 guy once end of last season, whats that bird there your sending, all ruffled up, dirty wattle, he said it only came back wed, so its got to earn its corn!!! 99% sure he never seen that bird again, deffo was just not flown out, slimy green droppings, I loved to keep mine on just cider vinegar, yoghurt, etc. but i dont think its possible when there are so many sick birds on the lorry, just so they can try and win averages etc.
