In the last 2 weeks I have found 2 hens dead in the coop. Neither were the result of fowl play ( no pun intended ) Both were hatched in Feb. of this year. I have a flock of 20 including one rooster. They have a very large coop with good ventilation. Are fed and watered well ...have good weight and no signs of illness. They free range in the barnyard all day and are put up every night. The night before the first girl died last week i noticed her just sitting on the ground outside the coop around roosting time. She sat out there until dark and finally did go in for the night. She was dead the next morning. I found the one dead in the nesting box this morning. Our night have been in the 20's but I dont think its the cold. I would really like some info if any of you have ideas. Thanks!
