Thanks guys.
We don't have much of a problem with pigeons here, certainly not in the area where I live. We do have an edible Dove species called Ramier, not that I actually hunt them, I just try to protect my free range chickens from varmints like Mongoose.... which seems to be mostly my dogs job, it caught and killed one, and has chased 2 to my knowledge. Unfortunately it also seems to like iguana, luckily I rescued one literally from the jaws of death yesterday, and then we have rats and mice who love the chicken feed, also as I said before the occasional predatory chicken hawk.
