ok, i hate to kill something but we have lost two birds and tonight was there was a third unsuccessful attack thanks to our lab. i did put out poison after the live trap failed. our birds are in dog kennels and i could add smaller wire around them, but electrifying will take time, so is there anything that will deter them? we plan to leave the dogs out tonight and i know it ate some poison, but any suggestions? i also feel rotten about this, but what else?
