I have 19 hens and 2 roos. I work all week so I currently only let the chicks out on the weekends. I live somewhat secluded on 5 acres with on kind of close neighbor that has a dog. I want to let them out every day so that they get more of a natural diet instead of the non GMO grain that I throw out every night once they have gone in to roost. I need input and thoughts on whether or not the two roos will be able to protect the flock.
