Hey, I'm hoping for some expert advise, or any random ideas would probably be helpful too. I live in central Pa and have 5 or 6 year old hens. ( I can't remember what year I got them) I've lost many of my hens to foxes, mostly the flighty ones that can't stay put in the fence. Last winter I lost one to what I thought was sickness. It was this time of year (COLD) and she got really slow and inactive for a few days, didn't move around much and several days later she died. She would've been 4 or 5 years old. I assumed she caught something and died. In the summer, I had the same thing happen one in the beginning of the summer, and one just recently at the end of summer, at that point it was 90 degrees and I too just figured some sort of sickness from the heat. Now I am wondering, because back in October, when we had a cold snap with some snow I noticed one was acting slow and inactive and she died a few days later. When the October hen died, my wife asked me if I noticed that Lumpy was acting the same as the others that have died in the past. I did. But she went from October to today doing normal chicken things with the rest of the flock, just at a much slower pace. She died quicker than the others. The others had a 24 hours or so stretch of time before they died where they wouldn't eat, scratch, drink or anything. I didn't notice that with the one that died today. I did notice the slowing down, not flying up on the roost with the rest at night (She just slept in a hay pile on the floor) but just last night she was out and about with the others. I found her this afternoon dead. Any ideas? 5 or 6 seems young for a chicken to die of old age. Maybe a virus is getting passed around in the hen house?
