I have three separate coop areas, a 10 x 12 raised hen house that was built on poles like a pole barn, completely enclosed and shut up at night, a stall in a lean to shed attached to the barn, and a 12 x 12 stall in the horse barn. After finding a skunk in the stall in the lean to shed one night I invested in NiteGards and have had no problems since....UNTIL....drumroll here........last night. The 12 x 12 stall in the barn is where i raise baby chicks I hatch and purchase...there are probably 400 little chicks in there and I move them out as they get bigger....Last night, something dug under the stall wall from an adjoining stall. I had no dead chicks out in the middle, but there were 20 dead chicks behind two oak doors that I had laid on their side and leaned up against the wall. The chicks behind door number 1 were mostly just dead, three were missing heads and one still had its head but was missing it's intestines. I am perplexed....there were some scattered feathers near the doors but now what to do? I close the barn doors at night, but there is room for a small animal to go under the doors....and now that whatever it is knows there is helpless lunch in there...I am unsure what to do....I did not have any of the nite gards on the barn doors. I could A. Leave my dog shut in the barn tonight and hope it is not a skunk so I dont have to do the skunk smell bath tomorrow.. B. Move all the chicks to the 10 x 12 hen house...where they would be overcrowded because there are laying hens in there but they would surely be safe... C. Sit out there tonight with the pistol and hope I don't miss when it comes back. D. Surround the stall with an electric fence. (Do electric fences deter determined hungry predators? E. I do have live traps and am thinking perhaps set a trap with some eggs and some sacrifical chicks in it to try and catch it. I am open to any suggestions for any other solutions. I don't have a husband or boyfriend to help and dont know if I can get the handyman to come by today. I know I have skunks, and my daughter had a troublesome raccoon last year but she lives a mile away. My neighbor said he saw a fox last week. I live in the middle of the prairie, there are no trees for cover for over half a mile so I have had little problems before. I now realize that I should not have this many chicks and will advertise to try to sell them rather then lose them...but the cabinet incubator had great success and it was addicting....(Oh, I will hatch just a few more eggs). Thank you for any and all help.
