This is only one grandma's opinion. I cried when I read your statement. Having gone through the trauma of having a hateful neighbor (for no reason except insanity) who wanted to kill all my birds, who threatened me, who harassed me on end, who shot at my house and wound up with a restraining order against him.... I say this: I would gather up all the good people here, make a worthwhile statement with all the facts, have all of us sign it (I would be willing to be the first), and post it public to the newspaper, to your local TV station (as a public service of course), to Animal Planet, to the world. Irresponsible pet owners get on your knees because we are not going to take this laying down. I have no extra cash to give you, but I will give up some grocery money to send something along with all the others who may be willing, just so you could accomplish such a mission.
For the record, in my case, I presented a case to my City, without the help of a professional, and although it took a bit more than a year, my City actually HEARD me and changed the ordinance in my favor. The nasty creepy neighbor is gone, and I can now live in peace.
I encourage you to do whatever it takes to make things right, even if the thrust is not against Mr. Gapp himself.
Many hugs from a chicken mom in California.
