My husband and I are really new to owning chickens, and last night something got 3 of my 7. We keep them in a sectioned part of our workshop, so there's a concrete slab and outside walls (of course we laid a thick layer of hay for them), so I know nothing burrowed in. We do have one outer wall that is 3x3 metal squares, so we ran 1" hex along the bottom in 2 rows, so it goes up to about 5 feet or so off the ground. I apparently underestimated what could get in there at night. One of the chickens was completely gone, just a small pile of feathers, one was torn into many pieces, but kind of stacked back together, and the third I couldn't find a cause of death, maybe it got scared to death? I've been reading online all morning, and I have a feeling it's a weasel, although I haven't seen any out here. Does anyone know if they're in my area? I live in Bonham, Tx, north of the Dallas area near the Oklahoma border. I still have 4 girls left, so I know I need to come up with a solution before dark tonight. I'm thinking of getting some 1/2" fencing and running it in place of my hex, but I'm not sure how high to go? Since it's my workshop, it's 9 or 10 feet tall, so do I need to run the 1/2" all the way to the top? Sorry so many questions, I really want to make sure this doesn't happen again!
