Unfortunately yesterday I found one of my favorite Barred Rock hens dead. She had been killed and pulled through the fencing (I didn't get a picture). I saw some chewing on a few boards on the outside, but framed our newest cat. I thought for sure this cat killed my chicken, but then this morning I found some new evidence that might prove his innocence. I have digging around the posts of the fenced in area. It doesn't seem big enough for a dog and there aren't any tracks left behind (which makes me think it certainly isn't a dog). The ground is soft out there and I can usually spot dog tracks no problem. I'm concerned this is a fox or coyote, because I know for a fact I have a large red fox living a few feet away from my coop (I've spotted him numerous times). Take a look at these pics and let me know what you think. I'm at a loss for a solution, and don't have access to any traps or the money for a trail cam. Any advice?
