My mom keeps bugging me that I need to put all but one of my roos in the freezer because they will fight and kill eachother. The pen they are currently in that may be true, but we are working to fence in a large portion of our yard so they can free range and they will have plenty of room. I have 16 hens and I want some fertile eggs to sell when they get old enough to start laying, so from that I was thinking I needed to keep 2 or 3. I've heard of other people being able to keep roos together as long as they have room to keep out of eachothers "territory". Will I be ok keeping 2-3 roos, or is she right that I need to butcher all but one?
