Wow, a bunch of interesting posts. I think, even though we have done a lot of proofing, we are probably still vulnerable. The strange thing is you can go for several years with no problems and then a predator decides to get in and you have to deter them or give up. I think making your coop as predator proof as possible is the best course because once they know there is easy, high quality food there it is hard to deter them. I am thinking of an electric wire to deter them, preferably solar powered. Any good recommendations?
Premier1 for electronetting. Expensive, but so worth it! I wouldn't even bother trying to have chickens if it weren't for this option, but having it allows them to practically free-range. They have a mind-boggling array of charger options. I was completely new to this when I got mine; their customer support is very helpful, but you have to know what to ask. I wanted the solar charger too, but it has to placed in full sun. I don't have that here, so I went with a battery charger. Works fine. My only predator loss was when one of the wires came off the charger and I didn't notice.
