My wife's pet chickens were all killed on Christmas. I think it was a Bobcat. One large bird, 10 to 15 lbs, was eaten. The other 5 killed and buried in the straw. The killer had to fit through a 8 in opening, and climb well. It found a small opening that I failed to secure. There are bobcats, mountain lions, ringtails, coyotes, and more in the area. I think I'm going to take up bobcat hunting. Any opinions on the killer?
