I disagree with your statement that says there is really no totally Fort Knox coop my coop is actually called Fort Knoxy it is the Ultimate coop as far as protecting my girls it is doubled wire welded fence on top of galvanized pole structure with double added center supports no seams all seams are lapped and protected barbed wire wrapped ties , galvanized welded floors so nothing can dig in or out , this is a three hundred and sixty degree protection ring. And to top it all off I have eight thousand volts of electricity surrounding the entire building !!! Nothing I mean nothing is getting my girls ?
