And FYI.....our coop is on stilts with the bottom wired in. I thought they were secure. Till the weasels got in last fall. My poor chickens had no escape route. Weasels chew. The only reason we were able to stop them was by catching them in the act. A month ago, new neighbors with big dogs, took out our turkeys. I lost two guineas 4 nights ago to a fox. I have one left....a very lonely, confused girl. I’m trying to locate some older chickens who are ready to be put out to pasture, for her to have company. So far the alarm has worked well. When she goes in for the night, I check her, then set the alarm.
