Hen Turned Mean then Died
Hello there. I have had a flock of laying hens for over 2 years now and they have been doing great. I introduced four new hens to the flock last july and they have all got along well. Two weeks ago though my brahma hen suddenly turned mean and started pecking the vent of another hen that she has been with since day one. Within a few hours she had pecked the other hen to death (I was not at home when this happened.) Then the next day she turned on one of the newer birds and begin pecking her vent. After a search through my chicken books I found that she could be needing extra protein so I gave my birds some venison I had in the freezer. This stopped the attacks thankfully. Two days ago I found one of my newer hens lying on her back on the floor of the coop totally paralyzed. She was awake but not able to move and had been fine just hours earlier. I ended up having to euthanize her. Then this morning I went out and my mean but otherwise healthy brahma hen was dead. She had also been the picture of health just a few hours earlier. Both hens were healthy and showed no symptoms. No scabs or sores, no mucus, no diahrrea, no changes in comb size or color, no weight loss, nothing. Any ideas what may be going on and how to treat it?
