Until today, we had one rooster and 6 hens in one coop. The coop is inside a chain link kennel and the kennel has blocks around the base and chicken wire around the chain link about three feet up. The top of the kennel has rows of chicken wire across it to protect the chickens from hawks. In addition, to protect the birds from the neighbors, we have a padlock on the door to the kennel. It is virtually predator and escape proof...so we thought. I went out to feed them today and they are all gone except the rooster. His feathers are everywhere (there are a few hen feathers but they are mostly his) and he is lying dead with his body hollowed out. The lock is still locked, the chicken wire is in place and although it looks like something tried to dig around the kennel close to where the carcass is, nothing dug under and the chain link and the chicken wire are untouched. What happened? Has anyone else ever experienced this?
So sorry for your loss. Most everyone who owns chickens has had a loss over time. I know I have had my share over the years. Do you have any idea how the predator got to your birds? One thing I would consider is to put up a game camera or some type of camera. The predator will be back and then you will know what you're dealing with. I have good strong heavy duty netting covering my pens, electric wires around my coops and pens and concrete under the gates all due to losses from predators in the passed. Lessons learned the hard way. I see predators quite regularly on my cameras. Often times they will lurk looking for an opportunity. Nothing has gotten past the electric wires and I do use chicken wire but also have some welded wire with chicken wire too. I also have a quite powerful fence charger so anything that touches the hot wires will know it. I did have a timer on my hot wires to turn them off during the day but on at night when most of the predators roam here. It died so now I have to remember to turn them off when I'm out around the coops. It may not be pretty but works. Good luck...
