So. I know we have foxes, I've trapped them. I know we have weasel/mink//marten because I've found the carcasses. Have raccoons, skunks and anything else short of coyotes and black bears. My coop is a few feet off the ground. 3' thick concrete floor. Very solid old garage. Everything is sealed off completely and the biggest gap I can wrench the door open to get to is about 1/2". I've put steel mesh along the edges of the roof and sealed them with 2" roofing nails, every 2". I've gone over everything with a fine tooth comb but I know for the weasel it's almost impossible. I've put two latches, on top and bottom of man door, both will be locked with pad locks. Also the same for the chicken door. I ain't messing around with those thumb using raccoons either lol. Anyone else in Central New York or anyone that has these predators, any feedback is appreciated. Tomorrow I'm going out to make a handful of "weasel trap boxes". May as well get pro active before my chicks go out to the coop. I think with my "Fort Knox" coop, the only thing that will be able to find a way in would be a weasel. If anyone has any tricks that work i.e. Blinking lights, chimes....Thank you.
