We bought from Murray McMurray last summer and ordered 25 hens in a
straight run order.
Straight run means the chicks are unsexed and you take your chances. If you
want all females, you order females.
Murray McMurray sends the exotics to seduce people into becoming chicken
fanciers, as opposed to raising them for food. If yours is the latter
purpose, drown the exotics upon arrival.
