I know this has come up several times, and I\'ve come up with bits and pieces searching the forum, but, if you guys don\'t mind, could you give a run-down of what you cull for in day-olds (buffs in particular) and at various stages of growth (if I haven\'t seen \"X\" by a certain age, I cull; as soon as I see \"Y,\" I cull)? Last year I dumped way too much feed into way too many birds for way too long, and I simply can\'t afford to do that again. I NEED to get rid of as many birds as I can as early as practical, so any tips/advice/suggestions would be greatly appreciated.
