I have been looking at pricing in my area and around others for Cornish X broilers. What is the difference between the Pullet, Straight Run or Cockerels? I would assume that Pullet is the female, Straight Run is whatever they grab you get and Cockerels are all males. If they are what I just listed then why the big price difference between them? Pullet - $0.89 StRn - $0.95 Cock - $1.06 And what do most people get?
