I had two chickens. Yes, just two. Small yard. About a week and a half ago here in MN the heat index got up to around 115 degrees. When one of our hens went into lay, she never came back out. She seemed to be the dominant bird - the one that died I mean. Now our other hen won't go back into the coop. She roots in a thick bush all night. We tried putting her back in the coop and keeping her isolated to just the run and the coop hoping it would fix the behavior, but it hasn't. This bird also stopped laying. She gave us eggs for about 4 months straight. Stopped. Gave us about 2 1/2 weeks more and then stopped and hasn't started again. She'd stopped before the other hen died. The other hen laid right up until she passed. Any thoughts on how to "fix" either of these behaviors?
