after losing 5 almost grown austrolorps to a varmit I installed two hot wires around the bottom of my run,plus hardware cloth around the bottom,plus two hot wires around the top ,covered the top with hardware cloth,the slide latches are ok if you get the ones with the holes in the slide so you can install padlocks,I installed those and put eyebolts and chains on my outside nest box lids,with padlocks
installed an apron around the bottom of the run about 18 inches out with steel wire,plus i purchased four of the night guard flashing lights,don,t know whats working but I have not had another loss to varmits in over a year,raccoons are very persistant and wise killers,they can wipe out an entire flock in a few nights,,and I also use traps on my property baited with sardines,I have a lot of time.money and labor in my hens and will protect them in everyway possible,I don,t relocate,that only adds to someone elses problems,transports possible deseases and moves one animal onto the grounds of another.leading to a possible fight to the death,you have to do whats needed to keep your flock protected because if raccoons can get to them,they will destroy them,and its not a pretty thing for a small child to witness
