We live in NW Louisiana...and have many predators such as racoon, opossum, armadillo(not sure if they are predators), fox, and hawks. Just learned that a friend lost a favorite polish hen to a mink. We have not put our chicks out yet, but our run is constructed of galvanized welded wire fence with 2x4 holes. We buried it as well as put a rock apron around the perimeter and the top is also fully fenced and partially covered with shade cloth. The chickens will be secure in their house at night...if anything gets in there they will need dynamite...but I am concerned about mink and their daytime habits when the hens are in their run? Are they small enough to fit through a 2x4 opening? Compared the the dog yard which is adjacent and fenced in chain link...the holes seem smaller. Also...will the predators be as likely to come around with two beagles close by? Since I am not familiar with mink...I am not sure what to expect?
