well in many cases there is just a heap of feathers on the ground (all near the coop) with a trail leading into our thickly wooded forest, but on one occasion and probably the most oppsetting was when the animal got to the families 'pet' hen, she had recently had chicks and decided to hide in the hay at night instead of in the coop, and i thought this very unsafe since for the past three morinings we have found our hay scatterd and lids off our feed cans and brushes and buckets tipped off shelves so at night I would take her and her chicks into the chicken house. but on friday we were leaving for kansas and didnt get back till late tonight so I placed the chicken (whos name is chicken little) into a cage and placed it in the chicken house and we also for the first time in a long time locked our other chickens in the pen surrounding the coop, but unfortunatly our ''animals'' babysitter didnt realized that she had to shut the door to the coop up so when we came home the wireing had been clawed through and the criiter had easy acces inside the coop. How the animal managed to get into the cage without opeing the door (which had three hooks keepin it sealed tight) with chicken Litte and drag her and her five chicks out is beyond me. (it also managed to grab two of our other Hens as well)
so obviously we have a very smart criminal mind on our hands which leaves me to belive it is the doing of a racoon.
