I know how you feel with the guilt but I envy you for your ability to do it. I can trap them but have yet to kill one. My wonderful husband takes care of them once they are in the cage. Usually drown them sense we live on a lake. I have had seven in the last two weeks! I even found a family living in a tree with in my electric fence in the pasture!! Was unable to shoot then when we found them due to a fairly close neighbor so now setting traps. I to have caught cats (my own), rabbits (also my own escapees), and even one of my Corgis! They eat better then me, yet get caught in live traps:/ Anyway, the coop is secure, electric on, and I put the dogs in with the birds at night. This keeps them safe from coyotes, and as soon as the coon might get in, they will kill it. It is an ongoing problem for us living in the timber. The best defense for me is dogs that hate them! Best of luck!!
