I opened the coop door once and came face to face with a snarling 'possum who was holding down a chicken with one arm while eating her eggs. I guess she was going to be dessert. All 13 ducks (although 'flyless') wound themselves up one day and flew away in a big swirling cloud of dust.
I had a flock of Frizzles but someone broke the lock on my gate and stole them all. Most of the Silkies had lethal accidents - they aren't very bright. A couple of them literally ran under the wheels of my husband's tractor. Then all 25 regular chickens were killed by a coyote teaching her pups to hunt (inside my chicken yard). No more chickens. The geese were finally killed, at age 20, by a mountain lion.
In between, there were encounters with skunks, hawks and Bobcats. Somewhere in there, the kids went off to college so I had to take care of all those birds by myself. After my geese were killed, I was done. I miss them. Only the geese, not the chickens. Sigh!
