A few have expressed concern regarding the rat bait I suggested. As I said previously, it's not a one bite. They have to eat the bait for several days, to get enough into their system, at a steady rate, for it to do anything. It's not exactly a poison, but rather an anticoagulant (blood thinner). When I bait, I do look for the dead ones, and bury them. I do know a hawk that did eat a dead rat, when I was trying to get it buried. It flew right next to me, and scooped it up, as I was digging the hole. It's still around, and still fine. If they ate several of the rats, for several days in a row, it might be enough to affect them, but it's doubtful. Rats carry a lot of parasites, and diseases. I'd rather not have them in my coop, which is why I occasionally bait them. My chickens won't eat the dead rats, so that's not a problem. Pinkies they'll eat. I'm not sure about mice. I never see any mice. Just rats, at times. Some years seem to be worse than others. I don't just toss poison out, and forget about it.
