Shortly after dark I drove bike to store on honeydo errand. Upon return I noticed my cooped birds were giving the low intenisity disturbance call. I ran into house for flashlight and as coming out door swept lightbeam across coops and saw two eyes close together shining an orangish-red, therefore knew oppossum before able to see body outline. I sprinted to the pen with the critter. It was standing on roost where my extra Privett strain dominiques would normally be roosting. The pen was still propped up to allow birds to enter for roosting and get cover from hawks during day. The doms had bolted. When I got to pen, the bugger made no effort to get away. I looked down and could see a pile of feathers taken from neck of one of the pullets. She got away. I attempted to reach down and grab the critters tail but my arm was to short for good grab. When I touched the oppossum it bolted, in typical slow run for such a critter. It ran to a another pen and ran through the material almost without slowing down, in one side, out the other. I was surprised it could do it. I ran around pen and caught up to it just as it was about to go through next pen. I caught it by tail as it was about halfway through and pulled the varment back and out. It tried to resist but oppossums are not that strong. Took critter to house for photographs. At no point did it try to bite, even when I put my shoe next to its mouth. Only had one do so in past and that was after repeated captures by me. I dispatched shortly after final photograph. It was one of few critters I worry about that 2" x 4" welded fencing would not even slow down. If a dog were in place, the critter would likely not have even tried to go after my birds. Killing to protect by birds does not make me feel better as thought originally. Gonna put more effort into getting a dog. Anyone in Missouri with Katahula pups?
