Well, when i went outside an hour ago, one was in the pen with my bantam salmon faverolle pullets. i worked on sealing up that pen as best as i could, which is a good idea in any case. i will stop putting the peanuts out. But i have to keep feed in the pens for my chickens. i have no idea how one got in the other pen this morning - chain link completely covered in 1/2" hardware wire. ChickenDogDuck, thanks for the information and link. License or not, i'm afraid there are a couple that will have to be dispensed with. i hate the idea, but they are relentless and i don't want them spreading disease in my pens, or my kids getting hurt.
