woke up this morning to a dead chicken in the coop. Half eaten. Our coop is very secure with hardware cloth, heavy metal fencing on the ground around the coop, and a metal roof. The sides are 8 feet high with only a 3 inch gap between the top and the roof. Darn if an oppossum didnt get thru that 3" gap and my husband found it napping in a nesting box after destroying one of my girls. My great husband quickly boarded up those openings. And got rid of the oppossum. Im glad I didn't find it.
