We too have resorted to locking everything. Too many people come out here looking to " buy chickens" yeah,,,,ok...I dont trust them. We have 8 ft chain link around the perimiter of the runs....and a good lock( i hope) on the door to the coop. Now, If I could only remember every time...to grab the darned key! Our coop is several hundred feet from the house...and when its cold,rainy,or snowing...and you get all the way out there without the key...yeah, thats frustrateing!!
