Hi. I have a few chickens, ducks, and geese in a 1/4 acre area enclosed by a five foot field fence with an electric wire running above it. I have two Border Collie/Red Heeler 10 week old puppies in with the flock. Yesterday one of my Buckeye pullets disappeared. I checked the fence and found that the battery went dead. It is solar powered and we have had two weeks of cloudy winter weather. Sure enough, today another Buckeye disappeared. There are no feathers anywhere. Nothing dug under the fence. The pups didn't make any noise. There was snow on the ground this morning but no tracks anywhere. Anyone have any ideas as to where my chickens are going? I have tried so hard to keep them safe. I lost some during the summer and beefed up the fort and got the dogs. I am really starting to get discouraged.
