thanks everyone for the ideas on how to get rid of a raccoon quietly.  Oklahoma City Division of Animal Welfare will lend you a trap for a week and then they dispose of the animal for you when you return it.  Or, I could drown it, etc.  I don't think your suggestions were cold-hearted at all.  A predator is a predator and has to be treated accordingly.  (However,...a fox is more forgivable than a raccoon, I think.  
 Raccoons, are in my opinion, the cockroaches of the animal kingdom.  They and cockroaches will be alive and well after all other species fail to exist....)
I also would like to clarify, MaKettle, that that wasn't suppose to be their home.  I feel very, very responsible for the way their lives ended.  The first week I got my chicks, I sat down with my neighbor to make arrangements to build a coop.  He was out of a job, I needed a coop, I thought it was a win-win.  I offered him $400 plus material cost and I showed him my design, which has insulation for weather & elevated off the ground and no openings for rats or snakes or wild birds to come in, etc.  I read all the suggestions on making it predator proof.  But, the problem is, that living in the middle of cookie-cutter suburbs, the only predators I SAW were hawks.  When the chicks had to go out, I was disappointed to put them in a dog crate since the coop wasn't finished.  When the chicks no longer fit in the crate, I was extremely upset to put them in my children's playhouse.  I didn't want them in there, I didn't want to use the playhouse for that purpose.  But, they needed more space.  I thought it might be for a few more days, maybe a week, the days turned into several weeks without planning on it.  I thought all I had to do was keep my chickens in the house to avoid them being picked off by hawks.  That's why I put the duct tape on the windows...to keep the chickens in.  It was never designed to keep raccoons out (which I didn't know at the time ate chickens).  I had never seen a raccoon in my yard or any other animal besides a squirrel.  That my chickens were picked off and devoured was a surprise to me...which is why I needed to figure out what the predator was.  I loved my chickens and would shoo them inside the patio anytime I even saw a hawk shadow fly overhead.  Had I imagined that raccoons visited my yard, had I known that they ate chickens, I promise I would not have "spoon fed" them my lovely chickens.  I was naive (both in regards to predators and in my neighbor's timeliness in finishing my coop) and this is ALL MY FAULT and I know it and I accept it as an epic failure on my part; lesson learned.  I have apologized to my chickens (wherever they are now) for the horrible way I made them end their lives.  I didn't elaborate on this particular part of the story b/c it just didn't contribute to the information I needed to know, specifically how to rid the predator and how to proof the coop against the specific predator.
so, thanks for all the really great info & help in identifying the specific predator i need to proof against.
