Hi my name is Marie. I have had my chickens for 3 years now without much problems...until now. I had 8 chickens, 5 older chickens and 3 new that I added back in April. I was away for a week leaving plenty of water, food, greens and an open tunnel for roaming. I came back only to find the 5 older chickens with no trace of the 3 newer. This is not my first time leaving for vacation for a week. No predator has ever penetrated my coop for three years. I am a bit baffled. Any ideas as to what may have happened? Thanks.
