I am considering getting chicks in the future and I know ordering DP chicks straight run instead of pullets and I expect 60% roos because from what I have read on these threads they advertise 90% sexed but if you order their meat specials people on here seem to get 98% to 100% roos (seems strange to me on 90% accuracy). that being said I know it will be a while to be able to sex, but will I be able to get them bigger after they reach maturity using feed for Cornish crosses? or at least with any significant growth?
