look for something called "Just One Bite". But pick it up during the day, because the squirrels and chipmunks will eat it too.Thank you so much. I was afraid of going that route because I could never forgive myself if I accidentally killed one of my babies. (Yes I know they’re supposed to be farm animals, but they are really more my feathered kids than anything else!!)i think I am off to tractor supply to get some rat killer!! Wish me luck
