I'm not knowledgeable about chickens. You may want to start a new post thread and ask if anyone has experience with chickens and can give you some advice. I do have an aunt who kept chickens for many, many years, but she had lots of acreage, and the coop was a distance from the house. I remember her always having trouble with foxes getting into the pen & killing her chickens. She finally decided to give up!
My husband & I kept ducks for awhile, maybe 15 years ago. We had their pen outside, right under our upstairs master bedroom. I loved looking down on them at night before we went to bed! Unfortunately, a neighbor's dog jumped our fence & killed one of the ducks while it had been in the yard, swimming in the little pond out back. Then we went to court over his nasty dog, but it backfired on us because he'd discovered there was an ordinance against having "farm animals" in our township! That sucked! We were forced to get rid of the ducks! 
We did enjoy the duck eggs while we had them though!
