i am dealing with massive massacre at our home. came home to 2 dogs who had bowled through the electric fence (which wasn't hooked up). they got 6 birds. i left for work the next day and only let them out in the run that has a 7 foot wooden fence that it dug in a foot into the ground. it does not have a top on it. that afternoon after work, i noticed another was dead in the coop with a big chuck out of its belly. thought it must have been injured the day before. this morning i pulled one that had major injuries (i thought from the dog) into the house and cleaned the wound again, big gaping hole! have her in a pen in here. then tonight i went to close them in and another chicken was dead in the coop with a big hole in it. what could this be. i know there is a skunk nearby, but can they climb a 7 foot wooden fence? any ideas would be great. none of the chickens are leaving the coop (which is part of an old building with concrete floors and wooden walls built in the 40's) until i can be sure i am not going to lose another. we have gone from 28 chickens to 17 in a very short time. this sucks.
