I remember when first on this site and our hen topped the fed when someone on here asked how many birds were in race ! My answer was 350 ish to that the reply came back that did,nt mean sheet as the birdage was so low same hen was 1st fed 2nd sect 3rd open Snfc bovington 5500 birds also bred a 1st club winner before ybs all took ill and were disposed off, so George I don't think it makes any differance quality is quality.
