Ok so we have 4 new Barred Rocks and one is for sure a roo and someone else is looking mighty suspicious. They free range on 4 acres, can I keep both roos? And what are these breeding pens I'm hearing about? Are they necessary? Do I care? Can't I just let them out everyday and let them "go at it" for lack of a more meaningful term? I'm not even sure how to go about letting my girls hatch their own chicks. Do I let them? We don't have an incubator so I guess I don't have any choice.
