Farmboy has given some excellent advice. Have a rolling coop, and move it from place to place to fresh grass and fields.
The main point I am stressing here is the insanity of having a chicken coop up against your house under a deck. Would you go out every evening and dump a bucket of your family sewerage underneath your deck? I'll bet not. But, you are doing the same thing by raising chickens there.
And did I mention the constant influx of snakes, weasals, skunks, raccoon, and other vermins (many of which carry rabies), that will be trying to get into that pen every night? And sooner or later, especially the snakes and raccoons, will find their way in. How wonderful to surprise a skunk one evening, have it spray down the side of your house (or the foundation dirt), and render it unliveable for weeks or months to come.
No, if you like eggs, please raise your chickens safely, away from your family. Some poultry borne diseases are incurable.
And, I'm laying odds that after 6 months of fooling with these things, you will have them hanging upside down from your clothes line.
Tell ya what. Print out my two e-mails, let your wife read them, and then let her decide. :-)
