I visited a brooder last week looking to buy black sex links. The owner showed me Rhodies, Barred, and Buffs, but said he gave up on cross breeds because they require more feed and nutrients. I scratched my head over that one. My only thought is a hybrid is usually a larger bird and may eat more, but a chicken is a chicken and I can't seem to grasp his meaning. Mine will free range most of the day and I'll provide proper water and feed of course. Even in winter they'll find plenty of seed and other food around the place. Will anyone share your ideas on this? Thanks in advance.
