Straight run chicks means that none of the chicks are sexed prior to
filling your order. Some breeders and hatcheries will make it a point not to
look, and some who offer straight run chicks will try to make an effort
to keep the rooster to hen ratio to aaround 50% if possible.
Some breeds are also very difficult to sex at such an early age.
that is what I was thinking....unless you are able and willing to cull ie: put them in the freezer you better buy sexed! I bought 29 last year and over half....like 16 were roosters.
