I live in an area with many wild roaming chickens. I have 14 Buff Orpington's, one is a senior Rooster. A big, really big nice looking BO rooster. But today he lost his second near death battle with invading roosters. I let the flock free range during the day around my compost piles, but apparently the local wild roos want the territory as well. I witnessed a fight a month ago with my Orp Roo and a single wild Roo and by the time I could break it up my Orp was bleeding badly and lost one eye permanently. The wild rooster was less than half his weight, but obviously a much more agile fighter. Today I saw two roosters approach, and my same Roo, Bob II, defended the flock valiantly, but lost badly. I found him in shock not moving and bleeding from his head badly. The thinner wild roosters are very adept at jumping high and attacking violently, I was shocked. So, anyway, I took him in and got him hydrated and warmed, now he is standing and the bleeding has stopped. I think he will make it , but I guess I can not let them free range anymore unless I can stand guard, which I cant. So far, my Bob has taken 2 beatings for the team. I find it interesting that the wild roos never bother the hens only confront the rooster in charge.
