Hi, I was just wondering if anyone can tell me approximately what is the life span of Isa Brown chickens or ex battery hen farm chooks. For the last 10 yrs I often purchase Isa Brown chickens from the battery hen farm (or the black Australorp, think that is the breed name) at the age of about 16wks old. All my chooks are fine and fairly healthy until about the age of 3 yrs old and then they stop laying altogether and then for about 18 mnths after they stop laying I usually find they become sick on and off for a few mnths and then finally pass away. I have always been curious if this is the nature of the chickens life style/span as it just seems to be the pattern with all my chooks. My chickens are 100% free range during the day and are locked up at night and fed Red Hen seed and inside scraps each day. Is this normal of a chickens life? At present I have a chicken who as per normal with my chooks history, stopped laying about 12mnths ago (she is now approx 4 yrs old) and for the last 4 mnths has become slower but still healthy except for the last week, to the point where she is quite ill and this morning has her wings drooped out and her breathing is very shallow. Two days ago she seemed to pick up but I am guessing today may be her last as it’s the worst I have seen her but as I have mentioned earlier, this seems to be a common pattern with my chickens. Do other chook owners go thru this pattern also?
