Well, thanks for all the responses.  We finally finished the chicken coop and I'm currently using just the coop as a brooder for all my new chicks that I hatched out: french black copper marans, mille fleur d'uccles, blue laced red wyandottes, araucanas, and spitzhaubens.  (I'll only be keeping 6 chicks b/c of the coop size.)
We laid a cement pad down for beneath the run and coop.  We wrapped the entire run frame in hardware cloth & anchored it down into the cement so it will hopefully be inpenetrable.  All the window/vents are also covered in screen material.  Should I do hardware cloth too?  Do you think a coon could get through the vents?
Here are pics.  And, I know the coop is small, just rest assured that I will not keep more than 7 chicks, and 3 of them are bantam.
here is the coop before placed in the yard.  It is double-walled and insulated.
And, here is the view from my kitchen window so I can see well what's going on back there.
Also, I've put up a trail hunting cam, a Moultrie D-55 infrared.  Does anybody have any experience with this?  I tested it last night & it doesn't seem to pick up my motion when I walk by the coop.  Does anyone have any other suggestions?
oh, and there is hardware cloth over that top opening.  On top of that, we're going to put a vented cupola.  it's just not finished yet.  The plastic bag is just to keep out rain, but there is hardware cloth screwed into the opening.
