I currently have 1 mature rooster and two seven month old cockerels to my 33 hens. I didn’t plan it that way. I didn’t get the old hens butchered in the fall like I had planned, and my two hatchlings from October turned out to be boys. For right now, it’s working. BUT - I free range my chickens. They have plenty of room to spread out. I’m watching behaviors and looking for injuries. So far, nothing, but I have had chickens long enough to know that it could change in an instant. If (most likely) when it does, I will be thinning my herd of males. Mine will be rehomed to jars in my pantry.
