It's too late for my poor RIR roo... or else I would have posted this in emergencies. Now I just need some answers. I think my 5 hens broke the neck of my rooster. Here's what happened: The flock is all 5 months old and in the past several weeks the rooster has been getting increasingly frisky with the hens- grabbing them on the back of the neck, chasing them, etc. I chalked it up to him wanting the mate with them and decided this was normal and they would all work things out and finally let him do what he wanted to do. Whenever this happened the hens always let out a squeal. This morning I let them out of the coop to free-range since we'll be home. I heard a noise and saw the rooster chasing one hen who ran to the back of the house with the rest of the hens in pursuit (looking back, this was unusual- usually is the roo want after one of them the rest didn't care and if the hen ran away he didn't put much effort into chasing them). I heard more squealing from the back of the house, but ignored it. I continued to go walk the dog and when I got back 3-5 minutes later there were 2 hens in front of the house. I went around back to see where the rest of them were and that is when I saw the Roo (we called him Lil' Jerry) lying on the ground, not breathing. I frantically roused my husband, who inspected Lil' Jerry and found no wounds. We can only guess that the hens broke his neck. Has anyone ever heard of this happening? Was the rooster's behavior normal or was he being too aggressive? Should I be concerned about the hens turning on each other at some point? Thanks everyone and RIP Lil' Jerry.
