gosh, I'm sorry about your loss. i read somewhere that light will scare raccoons away and we were thinking about putting a sensor light at the chicken coop ( even though i have it chicken wired and fenced like fort Knox ) never can be too careful
A good fence will help, definitely. Have a look round the Predators and Pests section for tips from our members who had to predator proof their coops. Good luck!
Thanks to all who welcomed us. Since Friday, there is joy back in Butterfield Coop... We introduced a (slightly) younger EE/Araucana type pullet to our surviving Australorp and within a few hours they were tight friends. We corrected the security problems with our coop and continue to fortify our run.
