sad day on the farm

My hen with her six peeps were brutally attacked last night. The hen was killed and eaten, one peep is missing, two were found dead and three are now all that are left. I strongly suspect an opossum. I saw one crossing the driveway Tuesday night when I got home. I must have scared him off for the night, but he came back last night for his chicken dinner. So the three remaining peeps are in a more secure location and have been supplied with a heat lamp since they are now orphans and their mother isn't there to keep them warm.
